integral of sin^2(x) ∫sin²x dx | sin^2
March 9, 2023
The integral of sin^2(x) can be evaluated using the identity:
sin^2(x) = {1 – cos(2x)}/2
Substituting this identity into the integral, we get:
∫ sin^2(x) dx = ∫ {1 – cos(2x)}/2 dx
= (1/2) ∫ (1 – cos(2x)) dx
= (1/2) {x – (1/2) sin(2x)} + C
where C is the constant of integration.
Therefore, the integral of sin^2(x) is:
∫ sin^2(x) dx = (1/2) {x – (1/2) sin(2x)} + C.
