integral of sin(x)(sec(x))^3

\int sin (x) (sec (x))^{3} d x

\frac{tan ^{2} ( x )}{2} + C

Solution steps

\int sin (x) (sec (x))^{3} d x

Rewrite using trig identities

= \int tan (x) sec^{2} (x) d x

Apply u-substitution

= \int u d u

Apply the Power Rule

= \frac{u ^{2}}{2}

Substitute back

u = tan (x)

= \frac{tan ^{2} ( x )}{2}

Add a constant to the solution

= \frac{tan ^{2} ( x )}{2} + C
