Sin 55 cos theta

Webb16 apr. 2024 · sin (55) = cos (t) The easiest way is to know that one graph is a vertical shift of the other. so sine starts at 0 while cosine starts at 1 and doesn't get to 0 until you are at an input of 45 (or pi/2 degrees). so sin (x) = cos (x - 90) = cos (x + 270) and cos (x) = sin (x + 90) = sin (x - 270).
