Can somebody help me do these please.o (greater or equal to) y and (less than or equal to) 360 degrees.

1. sin(x/2)= √3/2

2. 2sin^2(x) - 7sin(x) = -3 when o (greater or equal to) x and (less than or equal to) 360 degrees.

3. and most importantly sin2(y)= 4y when o (greater or equal to) y and (less than or equal to) 360 degrees.

Thanks.
