Step-By-Step Guide: Finding The Antiderivative Of Csc^2X Using U-Substitution And The Power Rule Of Integration

∫csc^2x dx =

-cotx + C

To integrate ∫csc^2x dx, we use u-substitution. Let u = cot(x) and du = -csc^2x dx. Then:

∫csc^2x dx = ∫-du/u^2

We can integrate this by using the power rule of integration:

∫-du/u^2 = 1/u + C

Substituting back in for u, we get:

∫csc^2x dx = 1/cot(x) + C

Simplifying by using the reciprocal identity, we get:

∫csc^2x dx = tan(x) + C

Thus, the antiderivative of csc^2x is tan(x) + C.
