Can anybody help me with this equation? I am staring to think there is a mistake there....
I tried to factor it, but it does not seem right...
2sin^2(x) - 6sin(x)- 3=0
So, I calculated it and got appx: -26
I must be missing something, because I really do not know how to proceed from here...
I know how to use unit circle, but what is value of x, when sinx=-26??
I am veeery confused now....
