Hi all,

I need to solve this equation giving my answers for angle from 0 to 360 degrees.

1-2sin(squared)E + cos(squared)E = 0

My answer

E 1-sin(squared) E = cos2E

cos(sqaured)E + cos2E = 0

(cos E + 2) (cosE + 0) = 0

either cosE = -2 or cosE = 0


E =(inv)cos (-2) impossible

E =(inv)cos (0)

t = 90 or 270 degrees.

Is this correct. Any help appreciated
