How to solve for cos theta

Webcos⁻¹(cos(θ)) = cos⁻¹((19/20) So in the LHS we take the cosine of theta, and then take the inverse cosine, which is just theta, so we have θ = cos⁻¹((19/20). Also be aware that there … WebNov 3, 2024 · a ⋅ sin ( θ) + b ⋅ cos ( θ) = A sin ( θ + τ) = A ⋅ sin ( θ) cos ( τ) + A ⋅ cos ( θ) sin ( τ) You can express tan ( θ + τ) using cos ( θ + τ) = − + 1 − sin 2 ( θ + τ). You will get the result …
