This calculus video tutorial explains how to find the derivative of trigonometric functions such as sinx, cosx, tanx, secx, cscx, and cotx. It contain examples and practice problems involving the use of the product rule, quotient rule, and chain rule.

Here is a list of topics:
1. Derivative of the six trigonometric functions – sin, cos, tan, cot, sec, and csc
2. Derivative of Polynomial Functions with Trig Functions
3. Product Rule – Derivative of x^2 sinx and x^3 cosx
4. Quotient Rule – Derivative of Fractions and Rational Functions
5. Chain Rule – Derivative of Composite functions
6. Derivative of sin(5x), cos(x^3), sec(x^2), tan(sin4x), sin^2(3x)
7. Trig functions inside of other trigonometric functions
8. prove d/dx (secx) = secxtanx
9. prove d/dx (cotx) = -csc^2 x
10. trigonometric proofs

Amazing, Life Changing Tutor
Before I met Jonathan, I was struggling through most of my STEM classes because I was simply not studying properly. He taught me all kinds of new study habits that would help me to save time, raise my grades, and lower my stress. Jonathan was specifically tutoring me in vector calculus and is an amazing tutor on the subject. You will walk away from a lesson with a game plan knowing exactly what you need to do before your next session with him or before your next exam in order to do well in the course. I highly recommend him as a tutor.
