Can anyone help me solve these two problems
2sinx cox-1=0 Then I am not sure how to proceed
sinx (sinx/cosx)- sinx
Sinx^2/ cosx -sinxcosx/cosx I am not sure if I am doing this right?

It's easier not to expand.
Add 1 to both sides:
Take the arcsin of both sides:
Thanks for your help however the second function I am still having problem solving.
I narrowed it down to
sinx^2-sinx=0 factor sin
x=0, 90,180,270,360 degrees?

and because .
