Fuck this unit is hard.
Anywho - any help with this?
Find to the nearest integer, the values of x in the interval 0 < x < 180 degrees for:
3 sin (squared) x - 7 cos 3x - 5 = 0
I've tried putting it into the quad. formula to find the 2 possible solutions and finding separate Primary angles for each but my answers don't match those in the back:
36, 84, 156 (all degrees).
ASTC applies here btw
