Web1.5 = cot θ = cos θ sin θ hence 1.5 sin θ = cos θ. Squaring both sides we have 2.25 sin 2 θ = cos 2 θ and since cos 2 θ = 1 − sin 2 θ we have 2.25 sin 2 θ = 1 − sin 2 θ 2.25 sin 2 θ + sin 2 θ = 1 3.25 sin 2 θ = 1. From this, you can figure out the value of sin 2 θ. Taking square roots will tell you something about the absolute value of sin θ.
