Hi,

3sin(2x) = sin (x)

I managed to find two answers: 80.4 Degrees and 279.6 degrees but I don't know hot to get 0, 180 and 360 as answers, can anyone help me?

This is how I found the two other angles:

6 sin (x) * cos (x) = sin (x)

cos (x) = sin (x) / 6 sin (x)

cos (x) = 1/6

Thanks in advance,

Peter G.
