You can find the inverse of a quadratic function by completing the square. Finding the inverse of a simple cubic function, for example, f(x) = x^3 is easy. But finding the inverse of f(x) = x^3 + 5x^2 + 2x - 6 is very difficult, if not impossible.

Web2 Common vector derivatives You should know these by heart. They are presented alongside similar-looking scalar derivatives to help memory. This doesn’t mean matrix derivatives always look just like scalar ones. In these examples, b is a constant scalar, and B is a constant matrix.
