What is this
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...
