2sin^2(x)+3cos(x)-3=0
As simple as trig gets. Someone solve it |

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 |
