Find the value of sin (5π/12) sin (π/12). - Tardigrade

WebJul 23, 2015 · Explanation: By the half angle formula: XXXXcos( θ 2) = ± √ 1 + cos(θ) 2. If θ 2 = 5π 12. XXXX then θ = 5π 6. Note that 5π 6 is a standard angle in quadrant 2 with a reference angle of π 6. so cos( 5π 6) = − cos( π 6) = − √3 2. Therefore.
