integral of 6tan^5(x)sec^2(x)

\int 6 tan^{5} (x) sec^{2} (x) d x

tan^{6} (x) + C

Solution steps

\int 6 tan^{5} (x) sec^{2} (x) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 6 \cdot \int tan^{5} (x) sec^{2} (x) d x

Rewrite using trig identities

= 6 \cdot \int (1 + tan^{2} (x)) tan^{5} (x) d x

Apply u-substitution

= 6 \cdot \int u^{5} d u

Apply the Power Rule

= 6 \cdot \frac{u ^{6}}{6}

Substitute back

u = tan (x)

= 6 \cdot \frac{tan ^{6} ( x )}{6}

Simplify

6 \cdot \frac{tan ^{6} ( x )}{6} : tan^{6} (x)

= tan^{6} (x)

Add a constant to the solution

= tan^{6} (x) + C
