Cos = -1 2

Nov 09, 2020 · y = cos-1 (1/√2) So we can say that, cos(y) = (1/√2) We know that the range of the principal value branch of cos-1 (x) is (0, π) and cos(π/4) = 1/√2. So, the principal value of cos-1 (1/√2) = π/4. Problem 2: Find the principal value of the given equation: y = cos-1 (1) Solution: We are given that: y = cos-1 (1) So we can say that Click here👆to get an answer to your question ️ The derivative of cos^-1 (2x^2 - 1) w.r.t. cos^-1x is Sep 01, 2014 · I assume you want to solve this: 2cos^2(θ)−1 = 0. Add 1 to both sides.
