Hi guys, I have a quick question.(adsbygoogle = window.adsbygoogle || []).push({});

When integrating [tex]\int sin^2xdx[/tex], do you need to use the trig substitution [tex]\frac{1-cos(2x)}{2}[/tex]?

I was able to integrate it using just [tex]1-cos^2x[/tex] as my identity and even when I showed a calc teacher how I solved the problem, he doesn't believe me or my math for some reason even though I proved that the two methods get the same result but in a different form.
