LOL I know how to do the question.

I didn't want to give you the solutions, I wanted to guide you through so you could figure it out yourself.
my inbox is going to fill up soon,

first, do you have any idea on how to do this question?
8sin^4x-10sin^2x+3=0

(2sin^2x-1)(4sin^2x-3)=0 Just factorising

2sin^2x=1 4sin^2x=3

sinx=1\sqrt2, -1\sqrt2 sinx=sqrt3/2, -sqrt3/2

x=45, 135, 225, 315 x=60, 120, 240, 300

ASTC, remember that since it's plus and minus that you consider all 4 quadrants.
