Best ResponseYou've already chosen the best response.0It goes: 3(1sin^2(x))sin^2(x)=0 33sin^2(x)sin^2(x)=0 So 4sin^2(x)=3

Best ResponseYou've already chosen the best response.0okay.. so then sin(x)= sq root (3/4) but sin never equals the sq root (3/4) on the unit circle?

Best ResponseYou've already chosen the best response.0never mind. that would be the same as sq root (3) / 2 duhhh! hah i figured it out. thank you!!
