I've seen this monster before on Brainly. I can't imagine it being solved any way but by graphing it. I'm sure you see the complexity of it with double angle formulas and and then a break down of Cos2x and Sin2x on the right. I'm going to go to desmos and see what it will do. Maybe I can find a way to at least get an answer. And here it is. Blue is the cos function Black is the sign. The sin and cos functions are plotting in degrees, but I don't seem to be able get the x axis in pure degrees. I'm wondering if this is a good enough answer. The other student had much much simpler questions to answer, so I think graphing it is a legitimate result.
