Complex numbers allow solutions to equations like x2 + 1 = 0 by extending real numbers to include imaginary numbers. A complex number z is defined as z = x + iy, where x and y are real numbers and i is the imaginary unit equal to √-1. Complex numbers can be added and multiplied following specific rules, such as z1 + z2 = (x1 + x2) + i(y1 + y2) for addition and z1z2 = (x1x2 - y1y2) + i(y1x2 + x1y2) for multiplication. The inverse of a complex number z is calculated as z-1 = (x/(x2+y

Comparative analysis of x^3+y^3=z^3 and x^2+y^2=z^2 in the Interconnected Sets Vladimir Godovalov
This paper introduces an innovative technique of study z^3-x^3=y^3 on the subject of its insolvability in integers. Technique starts from building the interconnected, third degree sets: A3={a_n│a_n=n^3,n∈N}, B3={b_n│b_n=a_(n+1)-a_n }, C3={c_n│c_n=b_(n+1)-b_n } and P3={6} wherefrom we get a_n and b_n expressed as figurate polynomials of third degree, a new finding in mathematics. This approach and the results allow us to investigate equation z^3-x^3=y in these interconnected sets A3 and B3, where z^3∧x^3∈A3, y∈B3. Further, in conjunction with the new Method of Ratio Comparison of Summands and Pascal’s rule, we finally prove inability of y=y^3. After we test the technique, applying the same approach to z^2-x^2=y where we get family of primitive z^2-x^2=y^2 as well as introduce conception of the basic primitiveness of z^'2-x^'2=y^2 for z^'-x^'=1 and the dependant primitiveness of z^'2-x^'2=y^2 for co-prime x,y,z and z^'-x^'>1.

A Probabilistic Algorithm for Computation of Polynomial Greatest Common with ...mathsjournal
In the earlier work, Knuth present an algorithm to decrease the coefficient growth in the Euclidean algorithm of polynomials called subresultant algorithm. However, the output polynomials may have a small factor which can be removed. Then later, Brown of Bell Telephone Laboratories showed the subresultant in another way by adding a variant called 𝜏 and gave a way to compute the variant. Nevertheless, the way failed to determine every 𝜏 correctly.
In this paper, we will give a probabilistic algorithm to determine the variant 𝜏 correctly in most cases by adding a few steps instead of computing 𝑡(𝑥) when given 𝑓(𝑥) and𝑔(𝑥) ∈ ℤ[𝑥], where 𝑡(𝑥) satisfies that 𝑠(𝑥)𝑓(𝑥) + 𝑡(𝑥)𝑔(𝑥) = 𝑟(𝑥), here 𝑡(𝑥), 𝑠(𝑥) ∈ ℤ[𝑥]

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
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Complex analysis
Complex Numbers
Consider an equation, 𝑥2 + 1 = 0. No real number satisfies this equation. To allow for a
solution of this equation, complex numbers can be introduced. They are not only
confined to the real axis. This complex numbers are pairs of numbers that denote
coordinates of points in the complex plane.
Real numbers, including zero and negative numbers, integers or fractions, rational and
irrational numbers can be represented on a line called the real axis as shown below.
Thus, conversely corresponding to each point on the line, there is a real number.
The coordinates of A represent a complex number, (𝑥, 𝑦). Since B lies on the real axis,
the coordinate of B is represented by a real number and for a point C, it is
purely imaginary.
Thus a complex no. is defined as 𝑧 = 𝑥 + 𝑖𝑦 where x and y are real and i is an
imaginary quantity which has a value √−1 .

Properties of Complex numbers
1.Complex numbers, 𝑧1 = 𝑥1 + 𝑖𝑦1 and 𝑧2 = 𝑥2 + 𝑖𝑦2 are added as
𝑧1 + 𝑧2 = (𝑥1 + 𝑥2 ) + 𝑖(𝑦1 + 𝑦2 )
2.Two complex numbers, 𝑧1 = 𝑥1 + 𝑖𝑦1 and 𝑧2 = 𝑥2 + 𝑖𝑦2 when multiplied yields,
𝑧1𝑧2 = (𝑥1 + 𝑖𝑦1)(𝑥2 + 𝑖𝑦2) = (𝑥1𝑥2 − 𝑦1𝑦2) + 𝑖(𝑦1𝑥2 + 𝑥1𝑦2)
3.Inverse of a complex number is found as in the following,
Let 𝑧−1 = 𝑢 + 𝑖𝑣 such that
(𝑢 + 𝑖𝑣)(𝑥 + 𝑖𝑦) = 1
𝑥𝑢 − 𝑦𝑣 = 1
𝑦𝑢 + 𝑥𝑣 = 0} 𝑢 =
1 + 𝑦𝑣
𝑥
𝑦 (
1 + 𝑦𝑣
𝑥
) + 𝑥𝑣 = 0
⇒ + 𝑣 + 𝑥𝑣 = 0
𝑦
𝑥 𝑥
𝑦2
⇒ 𝑦 + (𝑦2 + 𝑥2)𝑣 = 0 ⇒ 𝑣 = −
𝑦
𝑥2 + 𝑦2
Similarly 𝑢 =
𝑥
𝑥2+𝑦 2
Thus, 𝑧−1 = (
𝑥 −𝑦
𝑥2+𝑦 2 𝑥2+𝑦2
, ) (𝑧 ≠ 0)
4. The binomial formula for complex numbers is
(𝑧1 + 𝑧2)𝑛 = ∑𝑛
(𝑛

where (𝑛
) =
𝑘
Also 0! = 1
𝑘!(𝑛−𝑘)!
𝑘 = 0,1,2 … … … … … … … 𝑛
5. The equation |𝑧 − 1 + 3𝑖| = 2 represents the circle whose center is 𝑧0 = (1, −3)
and radius is 𝑅 = 2 where |𝑧| denotes the magnitude and is defined as √𝑥2 + 𝑦2
|(𝑥 − 1) + 𝑖(3 + 𝑦)| = 2
Thus, (𝑥 − 1)2 + (𝑦 + 3)2 = 22
So the center lies at (1, −3𝑖) in the complex plane and the radius is 2.
6. |𝑧 + 4𝑖| + |𝑧 − 4𝑖| = 10 represents an ellipse with foci at (0, ±4).
