2sin^2(x)+3cos(x)-3=0


As simple as trig gets.

2sin^2x + 3cosx --3 = 0
2(1 -- cos^2x) + 3cosx --3 = 0
2cos^2x --3cosx + 1 = 0
(2cosx --1)(cosx --1) = 0
cosx =1= cos0 or cosx = 1/2 = cospi/3
x = 2npi radians or x = 2npi +-pi/3

are we good

I did a little bit of trig in geometry enriched this year, but I'm too lazy to look at a problem in roblox's format...

2sin^2x + 3cosx --3 = 0
=> 2(1 -- cos^2x) + 3cosx --3 = 0
=> 2cos^2x --3cosx + 1 = 0
=> (2cosx --1)(cosx --1) = 0
=> cosx =1= cos0 or cosx = 1/2 = cospi/3
=> x = 2npi radians or x = 2npi +-pi/3 radian
