I am not too good with trig identities. I cant seem to figure out how to simplify these trig intergrals. I know I can use a triangle to turn the second problem into a trig integral, but once I have the trig integral, I am lost. Any help would be greatly appriciated.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int\frac{1}{x^2&\sqrt{16-x^2}}dx[/tex]
