integral of (1-cos^2(x))/(sin(x))

\int \frac{1 - cos ^{2} ( x )}{sin ( x )} d x

- cos (x) + C

Solution steps

\int \frac{1 - cos ^{2} ( x )}{sin ( x )} d x

Rewrite using trig identities

= \int sin (x) d x

Use the common integral:

\int sin (x) d x = - cos (x)

= - cos (x)

Add a constant to the solution

= - cos (x) + C
