Integrals of Trigonometric Functions
| Function | Integral |
|---|---|
| sin2x | x/2 - sin(2x)/4 + c = (x - sinx ∙ cosx)/2 + c |
| cos2x | x/2 + sin(2x)/4 + c = (x + sinx ∙ cosx)/2 + c |
| tanx = sec2x | -ln|cosx| + c |
| cotx = -csc2x | ln|sinx| + c |
What are examples of trigonometric functions?
Trigonometric functions are functions that relate an angle in a right angled triangle to the ratio of two of its sides. Sin , cos and tan are trigonometric functions.
What is the integration of sin2x?
Integration of sin2x means finding the integral of the function sin2x. Integral of sin2x can be written as ∫ sin2x dx. Here, we need to find the indefinite integral of sin2x. So, the integration of sin2x results in a new function with arbitrary constant C.
