My answer is:
Please help and see if its correct if not please help me!!
sin 4x = 1/2
4x = pi/6 and 5pi/6 now divide by 4 to find x
Yes you divide both sides of the equation by 4 so pi/6 would be divided by 4 also
I know i have asked many questions but is it correct?
2.1 for pi/6 and 10.5 for 5pi/6
