Differentiation of Trigonometric Functions
It is possible to find the derivative of trigonometric functions.
Here is a list of the derivatives that you need to know:
d (sin x) = cos x dx
d (cos x) = –sin x dx
d (sec x) = sec x tan x dx
d (cosec x) = –cosec x cot x dx
d (tan x) = sec²x dx
d (cot x) = –cosec²x dx
One condition upon these results is that x must be measured in radians.
Applying the Chain Rule
The chain rule is used to differentiate harder trigonometric functions.
