Quadratic Approximation

In this video I perform a quadratic approximation on the equation sin(xy) + cos(xy) and plot the results using a C++ Matplotlib library created by a GitHub user named Lava. In the previous video on Gradient Descent I show myself forking the repository and making changes to it.
The original plotter library link is:
github.com/lav...
The link to this code is located at:
github.com/MoQ...
Error: In the Jacobian vector function there is a small error in the last derivative where I put y0 instead of x0. The reason why this error did not show up in the video is because we used the same x0 and y0 values.

Perfect 👌.
