The tutorial code uses exp(x) but the documentation incorrectly stated it was learning sin(x). This fix updates the documentation to correctly describe what the code does:

  • Changed documentation from sin(x) from -π to π
  • To exp(x) from -1 to 1
  • Added explanation about Taylor expansion of exponential function

The code remains unchanged and continues to demonstrate fitting a polynomial to the exponential function using PyTorch autograd.

Fixes #3632
