Solution of a cubic equation
WebAug 31, 2016 · transform the reduced cubic (1) to match (2). To do this let t = A cos ( θ) and substitute in to get. (3) A 3 cos 3 ( θ) + A p cos ( θ) + q = 0. Now multiply (3) by 4 A 3 to give: (4) 4 cos 3 ( θ) + 4 p A 2 cos ( θ) + 4 q A 3 = 0. To match (4) with (2) we need 4 p A 2 = − 3, and so A = 2 − p 3, hence we need p < 0 for A to be real ...
