Did you know?
Webb29 maj 2024 · The general answer can be achieved by noting that you want to have a * sin (t) + b * cos (t) = A * (cos (c)*sin (t) + sin (c)*cos (t)) This leads to a simultaneous equation a = A * cos (c) and b = A * sin (c). Dividing the second equation by the second, we can solve for c. Substituting its solution into the first equation, you can solve for A. WebbSine, Cosine and Tangent.
