If you have time, watch the MIT lecture on Jacobian Matrices by Alan Edelman & Steven G. Johnson, & honestly, it may changes how you look at derivatives.Instead of treating derivatives as just formulas, they explain them as transformations of space. With proper rotation of images on live classes. haha Things they covered:- Difference between linear and non-linear transformations- How matrices act like operators that reshape geometry- Why the Jacobian is the best local linear approximation of a f
