∫sec^5 x?

Okay my book got the answer of 1/4sec^4 x tan^2 x + ln|sec x| + C. How the heck did they get that answer? They go through it step by step but the jumps from each step are huge so I still don't understand how they got the answer.

Please post the solution you have and flag the steps that have jumps too large for you to follow.
