Cubic Equation Solver written in Swift.
I tested only iOS 10 - 12. maybe works fine macOS too.
// find roots of `ax^3 + bx^2 + cx + d = 0`
// returns only real number
func solveCubicEquation(a: Double, b: Double, c: Double, d: Double) -> [Double]I had to find y for any x in the cubic Bézier curve B(t) = (x, y).
so I had to convert them to cubic equations y = f(x) and solve...
