[tex]\int\sec^{5}{x}dx[/tex]

i need a hint on this problem, my teacher told us that we prob. can't solve it with the method we've just learned. i'm not sure where to look in the book, i've looked through it but i don't know what is the best method.

hint? plzzz and i'll post all my work :D

i thought of ...

[tex]\int(\sec^{2}x)^2\sec{x}dx[/tex]

[tex]\int\frac{\sec^{4}x}{\cos{x}}dx[/tex]

but neither led me anywhere :(
