Good morning folks, I have been recently stumped by a few of my son's homework calculus problems and was hoping for a little bit of help. I'm sure they are simple, the thing is it has been 20 years since I took this.(adsbygoogle = window.adsbygoogle || []).push({});

2cosx=sinx

sin(pi)/2x=1

sin^2x+sin=1 (find zeros)

coscot=2cos

tan^2/cos(90-x)

(sinx^x-cosx^4)/(sinx^2-cosx^2)=1

cosx(secx-cosx)

I appreciate all your help
