# How would I approach this integral?

1. The only idea I'm having is to use double angle but knowing it for tan I can also see it going insane and being too long-winded.

Unless I'm missing something using the double angle formula makes it nice and neat.

Very quick and not long winded

I wouldn't mind it for cos or sin but with tan it really doesn't look that way. Anyhow, I'll attempt it and see how it goes.

in particular tan(4theta) = tan(2theta + 2theta)
works out nice at a glance

It does indeed turn out to be quite more simple that I first thought, well thank you for the confidence, I have a very bad case of 'getting-scared-when-seeing-trig-in-integrals-with-multiples-angles'
