Find derivatives of trigonometric functions
How do you calculate derivative?
The first step to finding the derivative is to take any exponent in the function and bring it down, multiplying it times the coefficient. We bring the 2 down from the top and multiply it by the 2 in front of the x. Then, we reduce the exponent by 1. The final derivative of that term is 2*(2)x1, or 4x.
What are trig identities?
The more important identities. The Pythagorean formula for sines and cosines. This is probably the most important trig identity. ... Identities for negative angles. Sine, tangent, cotangent, and cosecant are odd functions while cosine and secant are even functions. Double angle formulas for sine and cosine. Note that there are three forms for the double angle formula for cosine. ...
What is the derivative of CSC^2(x)?
The derivative of `csc x` is `-csc x cot x` , The derivative of `sec x` is `sec x tan x` and. The derivative of `cot x` is `-csc^2 x`.
What is the derivative of sin cos tan?
The derivative of sin x is cos x, The derivative of cos x is −sin x (note the negative sign!) and. The derivative of tan x is sec2x.

The trigonometric functions are a final category of functions that are very useful in many appli-cations. Rather than derive the derivatives for cos(x) and sin(x), we will take them axiomatically, and use them to find the derivatives of other trigonometric functions. d dx sin(x) = cos(x) and d dx cos(x) = −sin(x)
