WebMar 22, 2016 · For question #1 you need to use the formula: sin θ = sin a θ = { 2 k π + a, k ∈ Z or 2 k π + π − a, k ∈ Z. and in the second case. cos θ = cos a θ = 2 k π ± a, k ∈ Z. In our example, in the first case a = 99 π / 5. Take advantage of the inequality to find all the appropriate k ∈ Z in order to define θ. Web1.5 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.
