Cos theta 3/4

WebJul 16, 2015 · Determine the general solution of the trigonometric equation: sin θ = 3 cos θ. So the first thing I think of doing when seeing this is making sure either side has the same ratio. I can do this using co-ratios, so: sin θ = 3 sin ( 90 ∘ − θ) sin θ = 3 cos θ. From here I get stuck; there are no values to compute a reference angle with.
