The form is associated with trig substitution, specifically . Hope that helps.
Hi. As usual, struggling with basic integration stuff I'm already supposed to have mastered. Could somebody point me in the right direction with the following integral? I'm thinking maybe it is a trigonometric type of problem, but that is just a guess. Played around with addition by 0 and multiply by 1 tricks, but nothing seems to have helped so far.
Honestly, when we went over trig substitution in my class, my teacher told us that secant, sine, and tangent were the three main ones we needed to know, and if we ever saw integrals in the forms:
then the corresponding trig functions would be tangent (1) and secant (2), while I already showed you sine. Makes sense, as
So you can see the similarities in the denominators.
