WebMay 14, 2024 · Before we use PyTorch to find the derivative to this function, let's work it out first by hand: The above is the first order derivative of our original function. Now let's find the value of our derivative function for a given value of x. Let's arbitrarily use 2: Solving our derivative function for x = 2 gives as 233. I'm aware many higher order derivatives should be 0, but I'd prefer if pytorch can analytically compute that.
