Based on the readings and content for this course.docx
Based on the readings and content for this course, which topic did you find most useful or interesting? How will you use it later in life? What makes it valuable?
Ans:
Well, there are many small but significant things in real life, that I understand, are related to maths.
For example the screen size of a TV or a laptop. When we say 14 inch laptop we mean the diagonal of the screen is approximately 14 inches.
This is a direct application of Pythagorean Theorem.
And depending on the shape of the room determines the formula for area that I use. For example, if our room was a perfect square (which none of them are) I would utilize the formula a = s^2, since our rooms our rectangle, the formula we more commonly use is a = lw.
Again I understand the amount of money we spend on gas can be modeled by a mathematical function.
When we throw a ball up, the time taken for it to come down can be modeled by a quadratic equation.
There are so many things.
I won't pick up any particular thing.
But after this course, I am able to look at many things in a more analytical way.
I can understand the mathematical logic behind them.
So all these are valuable to me
Do you always use the property of distribution when multiplying monomials and polynomials.docx
Do you always use the property of distribution when multiplying monomials and polynomials? Explain why or why not. In what situations would distribution become important? Provide an example for the class to practice with.
Ans:
The property of distribution is one important tool in solving the polynomial multiplications.
For example:
3x*(x+5) = 3x*x + 3x*5 = 3x^2 +15x
But this property is used only when one of the bracketed terms contains two or more terms of different order.
For example in the above case, the bracket consists of two different order terms, x and 5.
Let’s take another case:
3x*(x+2x)
This can be solved in two ways.
3x(x+2x) = 3x*x + 3x*2x = 3x^2 +6x^2 = 9x^2
Or we can say:
3x(x+2x) = 3x*3x = 9x^2
So in the 1st method we used the distribute property.
But in the 2nd case we did not.
So it depends on the particular problem and looking at the different terms we can decide whether or not to use distributive property.
Explain how to factor the following trinomials forms.docx
Explain how to factor the following trinomials forms: x2 + bx + c and ax2 + bx + c. Is there more than one way to factor this? Show your answer using both words and mathematical notation
Ans:
Actually I am not very sure how to answer this.
For me x2 + bx + c and ax2 + bx + c are not different from each other.
The 1st one is a special case of the second expression where a=1.
To factor the expression ax^2 + bx + c we first need to factor the middle term bx cleverly.
Now it's to be understood that not all trinomials can be factored. But some of them can be.
Basically, we have to write b in the form b= p+q so that p*q= a*c. This is the only trick.
Then ...
1. Think “Relevant ==> Simple ==> Intricate.”
2. Visualize “mastery blocks.”
3. Generate comprehensive examples.
4. Assessment.
5. End with lead to next topic.
This was my first slidecast. It may not be exactly synced and I'm not sure why since when I go to edit it, the ticks are exactly where I want, yet the actual slidecast isn't synced properly. So yes, please enjoy anyways >_>

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
3. Differentiate Me Four Times As shown, this question is asking for the fourth derivative of f(x). From the work shown here by Mr. K, you can see the common pattern as you make your way to the fourth derivative. That pattern being the fact that the exponent on the “thing” in the brackets is being decreased by 1 each time and the fact that you’re multiplying by 3 each time as well.
4. Differentiate Me Four Times Also take notice of the fact that the exponents from the previous derivatives are being brought down due to chain law and such as well. That would be where the 4! part is coming from in the answer.
5. Finding the Unknown “k” Mr. K said to just use your calculator for this question as it can get pretty ugly, kind of. But for those of you who wanted to know how to do it numerically, I’ve included my solution as to how to do that. Its basically the Fundamental Theorem of Calculus and for those who don’t remember what that was, it basically states that the integral of a derivative is equal to the change in the parent function along the given interval.
6. Tangent and Intersecting?! Looking back at this question, it wasn’t so hard afterall. I just failed at my reading comprehension. Anywho, the first part of this question is asking for the line tangent to the parent function between the two endpoints. To find that specific equation for that line, you’ll first have to find the slope of that line. So do your ∆y/∆x for the parent function and then you should find that the slope is equal to -2.
7. Tangent and Intersecting?! Now what about the specific (x,y) coordinates for that line? Well, that’s easy, you’ve found the slope haven’t you? And what’s one of the definitions of a derivative? Yes, it’s a rate of change or tangent line. Huzzah! Now substitute all the values into that handy dandy line equation given points (x,y) thing and solve! Now you can solve for the last part of the question which was to find the intersection. Look at your line equation, y-value is 31! No other choice has a 31 in it but choice c, question done.
8. Optimize That Area! There are a few other ways to solve this question, but I will explain using Mr. K’s method. First off, we should find the equation of the semi-circle. Basically just solve for ‘y’ since doing that will get you the function equation for the circle, which is the semi-circle. From there, write out the equation for the area of the rectangle.
9. Optimize That Area! Once you’ve gotten that, you can substitute in the value for ‘y’ and then massage the equation so that the 2x is within the square root. Moving onto the blue colored part, we are going to just take the part within the square root of A(x) since whatever is maximized within there is going to maximize the whole thing anyways.
10. Optimize That Area! Now, we find the derivative of a(x) so that we can use the 1 st Derivative rule on it in order to find our x-coordinate which has the maximum y-value. In this case, its +√32. Knowing that, we can now go back to A(x) and substitute that value in for ‘x’ and solve. You should end up with 64. Yay!
11. Accumulation Time This question follows the Second Fundamental Theorem of Calculus. “What’s that again?” you ask? Well let me refresh your memory, it basically states that if f is a continuous function on some interval [a,b] and an accumulation function is defined by the integral of parent function from [a,x] then the parent function is equal to the derivative, or accumulation function of that parent function. So as you can see in this question, all you’d have to do is arcsin(0.4) since the derivative is equal to the parent function anyways.
12. Separation of Variables Mr. K didn’t show how get the answer, but I’ve shown how to get it just in case there were some people in class who were too shy to say that they didn’t get it. So here it is. This question is just basic separation of variables, such as when we were working with Newton’s Law of Cooling. Basically, after you’ve found the general solution and such, just input the given values and solve. Voila!
13. Derivative Rules Galore Like the title implies, we are going to use the first and second derivative to solve for all these parts. First find where the derivative has zeroes and then use your 1 st Derivative analysis line and find where the minimum and maximum is. Parts a and c are finished with just that.
14. First Derivative Rule Galore As for the inflection points, first find the second derivative and then use the second derivative rule analysis to find where the signs change. This is because an inflection point is where the graph changes concavity. Now that you’ve got that done, question solved.
15. There you have it. Our first mini exam review, which I’m sure we’re going to do some more of in the (few) days to come. Also reminders, the Wiki Questions are due tonight at midnight. After that time, Mr. K will close down the site so that no one else will be able to edit for the time being, or until we are given our next task of editing each other’s significant contributions. Oh yeah, and remember that our DEV projects are due soon as well. So get a move on with that if you haven’t already got it moving. Aaaand…happy milkshake chooses Paul as next scribe. That is all.
