Hi
Please can you help me to factorise the following equation to find the general solution;
\(\displaystyle 3- 2sin^2 x - 3cosx = 0\)
I multiplied the above equation by -1
\(\displaystyle 2sin^2 x + 3cosx - 3 = 0\)
and tried to factorise using the quadratic formula but I got a truly unfeasible answer
[-3 +/- (sqrt)(33)]/ 4
which makes me think that I'm not on the right track.
Thanks
