y = 3cos(pi*t) | 2nd derivative and acceleration Exam Question | Math Methods Unit 3 and 4 |
This motion video shows how to find the velocity and acceleration from the position function. The function is a trigonometric function y = 3cos(pi*t) and shows how to use the unit circle and exact values to find the time when the velocity is 0m/s and the acceleration when the velocity is 0m/s.
It requires us to find the first derivative and the 2nd derivative to solve this complex familiar unfamiliar question.
