I'm not totally sure how to do this problem. So far, I've done this:
=>
=
=>
From here, I don't know how to calculate the integral. Is there a trig identity that simplifies the problem? Do I have to integral by parts or substitution? I plugged it into wolframalpa and got a solution but it didn't give me what I really wanted, the steps on how to solve the integral.
Am I even approaching the problem correctly? Thanks
Thanks for the help. I'm not getting the tips for integration that you gave. For the first one, is that a trig substitution? And for the second one, am I supposed to used integration by parts or is that a substitution? I'm really terrible at integrating trig functions.
Thank you, I've computed the integrals now.
