hello everyone i can't seem to figure these few out....

solve these using fundamental identites...

here is an example of one i did...
u can use either side to start solving so it matches the opposite side.

sin^2x(1 + cot^2x) = 1

sin^2+sin^2xcot^2x

sin^2x + sinx cos^2x/sin^2x <---sin's cross out

sin^2x + cos^2x = 1 <----so there u go



1. cotx + tanx = secx cscx

2. sin^2x + tan^2 x + cos^2x = sec^2x

thanks all, later!
