WebGeneral cosine equation. The general form of the cosine function is. y = A·cos (B (x - C)) + D. where A, B, C, and D are constants. To be able to graph a cosine equation in general form, we need to first understand how each of the constants affects the original graph of y = cos⁡ (x), as shown above. WebWe’ll use three relations we already have. First, tan A = sin A / cos A. Second, sin A = a/c. Third, cos A = b/c. Dividing a/c by b/c and canceling the c’s that appear, we conclude that tan A = a/b. That means that the tangent is the opposite side divided by the adjacent side:.
