### Interactive Power Point Presentation

1. 1. An Interactive Presentation ED 205-16 By: Lindsay Schrauger 12th grade- Calculus
2. 2. Main Slide • Applications for derivatives • Average Velocity into Instantaneous Velocity • Slope of secant line into slope of tangent line • What is a derivative? • Example of finding a derivative • Practice Problems • Answers to Practice Problems • Video • Resources • Author’s Slide Quit
3. 3. Applications for Derivatives Throughout our study of derivatives, we will find that derivatives have several applications. There is a list below of the different applications. We will look at several of these applications throughout the presentation. The list includes: • Rate of Change • Instantaneous Velocity • Slope of the Tangent Line Quit
4. 4. Average Velocity to Instantaneous Velocity • Average Velocity over an interval [1,1+h] s(1+h)-s(h) (1+h)-h • Instantaneous Velocity at time t=1 hour lims(1+h)-s(1) h->0 h • Instantaneous Velocity is the Average Velocity as time intervals get smaller and smaller. Quit
5. 5. Slope of the Secant Line to the Slope of the Tangent Line As we can see in the picture on the right, the slope of the secant line consists of two points P and Q on f(x). • The slope of the secant line is found by finding the rate of change between (x0, f(x0) and (x0+Δx,f(x0+Δx)). • The slope of the tangent line finds the rate of change at a specific point P. Therefore, the slope of the tangent is the slope at (x0, f(x0)). Quit
6. 6. Definition of a Derivative The derivative of a function f, as written,f’(a) is defined as f’(a)=limf(a+h)-f(a) h->0 h Quit
7. 7. Example of finding the derivative Find the derivative of y=8x2+3 at x=a. y’=limy(a+h)-y(a) = lim8(a+h)2+3 - (8a2-3) h->0 hh->0 h = lim8(a2+16ah+h2) + 3 – 8a2+3 h->0 h = lim(16ah+8h2) h->0 h = lim 16a+8h = 16a h->0 Quit
8. 8. Practice Problems 1. Use the definition of the derivative to find the derivative of the function f(x)=x2+x at x=a. 2. Find the instantaneous velocity at t=2 when the function is given by s(t)=1/t 3. Find the derivative of the function s(t)=t2+8t+2 at t=a and t=3. Quit
9. 9. Answers to Practice Problems 1. 2a 2. -1/4 3. 3a2+8 and 35 Quit
10. 10. Video • In the video clip provided below, you are able to watch a tutorial of introducing derivatives, as well as view further applications of derivatives. • Teaching Derivatives Quit

12. 12. Author’s Slide My name is Lindsay Schrauger and I am a sophomore at Grand Valley State University. I am going into Secondary Education with a Mathematics major and Spanish minor. While I have always planned on teaching high school students, I have been gaining a passion to reach out to middle school students. I also plan on working with inner city students, where I can use my Spanish-speaking skills to reach out to Spanish-speaking parents. I hope you enjoyed this tutorial on Derivatives and if you have any questions or comments, please email me. Quit
