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

Question Why Is It That Cos1(cos(π/4)) = Cosπ/4shouldnt It = Cos(π/4) This problem has been solved!Let cos − 1 a b = θ, then cos θ = a b and 1 2 cos − 1 a b = θ 2 = tan π 4 θ 2 tan π 4 − θ 2 = tanThis code is configured to call cos_32s, which is the approximation (detailed shortly) for computing the cosine to 32 digits accuracy Use this same code, though, for all cosine approximations;
The exact value of sin ( π 4) sin ( π 4) is √ 2 2 2 2 The exact value of cos ( π 4) cos ( π 4) is √ 2 2 2 2 Simplify terms Tap for more steps Combine the numerators over the common denominator Add √ 2 2 and √ 2 2 Cancel the common factor of 2 25 π 4 and 7 π 4 both have a sine value of − 2 2, but neither is in the interval − π 2, π 2 For that, we need the negative angle coterminal with 7 π 4 sin − 1 (− 2 2) = − π 4 To evaluate cos − 1 (− 3 2), we are looking for an angle in the interval 0, π with a cosine value of − 3 2Arrow_forward Buy Find launch
