SOLUTION: Hello :) Could use your help on a question here :P Solve 4sin^2(2x)=3 when x is equal or more than 0degree but less than or equal to 180degrees Obviously I got to sin^2(2x)=3

Question 388726: Hello :) Could use your help on a question here :P
Solve 4sin^2(2x)=3 when x is equal or more than 0degree but less than or equal to 180degrees
Obviously I got to sin^2(2x)=3/4 but that's when the problem starts...
I am not sure how to solve sin^2(2x) as I've never seemed to have encountered simliar questions before and the internet just gives obvious stuffs that I already know.
Thank you very much! :D
