Cos cos^-1(-√3/2) π/4 190299-Cos cos^(-1)(-(sqrt(3))/(2))+(pi)/(4)

Cos^1(tan(pi/4)) find the exact valueIn the sum of angle theorems, let a = b so that cos (2 a) = cos 2 (a) − sin 2 (a) By the last identity, notice that cos 2 (a) − sin 2 (a) = 2 cos 2 (a) − 1 cos 2 (a) − sin 2 (a) = 1 − 2 sin 2 (a) Now let a = π / VarunRawat, Meritnation Expert added an answer, on 21/7/16 VarunRawat answered this We know that principal value branch of cos 1 is 0, π So, cos 1 cos 5 π 4 ≠ 5 π 4 Now, cos 1 cos 5 π 4 = cos 1 cos π π 4 ⇒ cos 1 cos 5 π 4 = cos 1 cos π 4 = cos 1 cos π π 4 = cos 1 cos 3 π 4 = 3 π 4 ∈ 0, π So, cos 1
