Examples using double angle formulas. example 1: if tan a = 3 4, find the values of sin 2a, cos 2a, and tan 2a. solution: since the value of tan a is given, we use the double angle formulas for finding each of sin 2a, cos 2a, and tan 2a in terms of tan. sin2a= 2tana 1 tan2a = 2(3 4) 1 (3 4)2 = 24 25 sin 2 a = 2 tan a 1 tan 2 a = 2 (3 4) 1. The double angle formula calculator has already done the job and found the double angles of sine, cosine, and tangent. for θ = π 12 \theta = \frac {\pi} {12} θ=12π , the double angle trigonometric functions look like this: sin ⁡ (2 ⋅ θ) = 1 2 \sin (2\cdot\theta) = \frac {1} {2} sin(2⋅θ)=21 ; cos ⁡ (2 ⋅ θ) = 3 2 \cos (2\cdot.
