Actually, I think I may have got it but can someone check my answers?
what do you get?
first what do you get for sin x?
4sin^2x - 3 = 0 sin^2x = 3/4 sinx = √3/2 or sinx = -√3/2
yes correct

So would my answer be x= pi/3 or 2pi/3 ?
it asks for values in the interval 0 to 2pi and the sine can be negative or positive so there is an angle in each quadrant which satisfies the equation.
So I should have 4 answers then right?
pi/3 and 2pi/3 are 2 answers
yes
