I really appreciated your help last time, now I have revision for an exam:(
Find values for x between -pi and pi if sin2x=root3/2
I know that sin(pi/3) = root3/2. I have been able to obtain values of pi/3 and pi/6, but the answers say that there are 2 more. I can't see the logic behind it, except I do know that you have to increase the initial range or something because it is 2x. I think.
Thanks in advance
