Some of the following trigonometry identities may be needed.
Below are the list of few formulas for the integration of trigonometric functions:
Integrals involving sin(x) and cos(x): Integrals involving sec(x) and tan(x): Let’s first notice that we could write the integral as follows, ∫ sin 5 x d x = ∫ sin 4 x sin x d x = ∫ ( sin 2 x) 2 sin x d x ∫ sin 5 x d x = ∫ sin 4 x sin x d x = ∫ ( sin 2 x) 2 sin x d x. The antiderivatives of tangent and cotangent are easy to compute, but not so much secant and cosecant.
∫ sin 2 u d u = 1 2 u − 1 4 sin 2 u + c ∫ sin 2 u d u = 1 2 u − 1 4 sin 2 u + c.

∫ cos 2 u d u = 1 2 u + 1 4 sin 2 u + c ∫ cos 2 u d u = 1 2 u + 1 4 sin 2 u + c.
Now recall the trig identity, cos 2 x + sin 2 x = 1 ⇒ sin 2 x = 1 − cos 2 x cos 2 x + sin 2 x = 1 ⇒ sin 2 x = 1 − cos 2 x. Complete table for trigonometric substitution. List of integrals of gaussian functions; Sin5(x) = sin4(x)sin(x) = h sin2(x) i 2 sin(x) = h 1 cos2(x) i 2 sin(x) and then integrate, using the substitution u = cos(x) )du = sin(x)dx:
∫ sin 3 u d u = − 1 3 (2 + sin 2 u) cos u + c ∫ sin 3 u d u = − 1 3 (2 + sin 2 u) cos u + c.
A.) b.) e.) it is assumed that you are familiar with the following rules of differentiation. Table of integrals of reverse trigonometric functions the first member of each equation contains the function to be integrated, the second member contains the expanded integral. Find the integral of any function using our integral calculator find out the value of the integral of a function covering any interval using our definite integral calculator. In the video, we work out the antiderivatives of the four remaining trig functions.
∫tan x dx = ln|sec x| + c;
∫cos x dx = sin x + c; In the past, we will have a difficult time integrating these three functions. ∫ tan 2 u d u = tan u − u + c ∫ tan 2 u d u = tan u − u + c. Up to 24% cash back derivative and integral of trig functions table 1.
