I am supposed to use trig substitution here. I used a tangent sub but then everything seems to cancel itself out. Which sub would I need to use here?
there is a straight forward formula for this, but if you want to do the trig sub, that's fine. you have an expression of the form thus your substitution must be . that is,

I couldn't think of a formula that this integral could fit. Which formula are you referring to?
