Webb13 jan. 2024 · Explanation: Because it is an even function, cos( −x) = cos(x) Similarly, because it is an odd function, #sin (-x)=-sin (x) So, the above ratio can be written. − sin(x) cos(x) which is equal to −tan(x) Answer link. 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. birch hill camps maine facebookWebbsin (θ) cos (θ) = Opposite/Hypotenuse Adjacent/Hypotenuse = Opposite Adjacent = tan (θ) So we can say: tan (θ) = sin (θ) cos (θ) That is our first Trigonometric Identity.
