4cos2x = 4sin2x+2
cos2x = sin2x + 1/2
let z = 2x
cosz = sinz + 1/2,
solve for z, then x=z/2
x = about 12.25 degrees and 246.5 degrees
Look at the graph of sine and cosine and you see that's the only areas between 0 and 2pi where
cosine could be about 1/2 more than the sine, 1st quadrant and 3rd quadrant
