I have to solve for X and am not sure where to start
questions:
cos2x +sin (squared root) x=0
where: sin(squared root) =1-cos(squared root)x
and
2 sin 4x + csc 4x =3
where csc=1/sinx
please, if anyone can give me a hand it would be much appreciated. Also, as I am a new user, could someone tell me where to find a squared root symbol?
