I'm doing a problem where I need to find the maximum curvature. I'm at a point where I need to simplify the denominator and reduce the funcitions in the bottom. I don't understand how to simplify:
[25sin^2(x)+9cos^2(x)]
To:
[9+16sin^2(x)]
What is getting factored out? Or is this completing the square somehow?
Thanks for any help.
