## Homework Statement

[tex]\int tan^5(6x) sec^3(6x) dx[/tex]

## Homework Equations

## The Attempt at a Solution

first off I set u=6x to get 1/6[tex]\int tan^5(u) sec^3(u) dx[/tex]

then I used trig identities to put tangent in terms of secant and I came up with

[tex]\int sec^9(u)-3sec^7(u)+3sec^5(u)-sec^3(u) dx[/tex]

Not sure where to go from here, or if I'm doing this the right way
