# Exercise 1: Taylor Derivatives Equal the Function's Derivatives at x = a

In this video I prove that the derivatives of a Taylor Polynomial are equal to the derivatives of the corresponding function used in the approximation when x = a. This is because any derivative at x = a of any Taylor polynomial cancels out all the terms (since a - a = 0) except the first term, which is just the corresponding derivative of f at x = a.

Timestamps:

- Exercise 1: Taylor Derivatives are the same as the function used in the Taylor Polynomial: 0:00
- Solution: Taylor derivatives cancel out all the terms except the first: 0:30
- n-th Taylor derivative is equal to the n-th derivative of f: 8:09
