integral of sec^2(x)*tan^3(x)

\int sec^{2} (x) \cdot tan^{3} (x) d x

\frac{tan ^{4} ( x )}{4} + C

Solution steps

\int sec^{2} (x) tan^{3} (x) d x

Rewrite using trig identities

= \int (1 + tan^{2} (x)) tan^{3} (x) d x

Apply u-substitution

= \int u^{3} d u

Apply the Power Rule

= \frac{u ^{4}}{4}

Substitute back

u = tan (x)

= \frac{tan ^{4} ( x )}{4}

Add a constant to the solution

= \frac{tan ^{4} ( x )}{4} + C
