Solve any equation using gradient descent

Gradient descent is an optimization algorithm designed to minimize a function. In other words, it estimates where a function outputs its lowest value. This video demonstrates how to use gradient descent to approximate a solution for the unsolvable equation x^5 + x = 3. We seek a cubic polynomial approximation (ax^3 + bx^2 + cx + d) to cosine on the interval [0, π]. www.instagram.com/edgardocpu/
