What is a simple proof of this differentiation property?

Click For Summary
SUMMARY

The differentiation property discussed is represented by the equation $$\frac{d^{2n}}{dx^{2n}}\left(x^2-1\right)^n = (2n)!$$. The proof utilizes mathematical induction, starting with the base case of n=1, where the equation holds true. The induction hypothesis assumes the property is valid for an arbitrary integer k, and the proof proceeds to demonstrate its validity for k+1, confirming the property for all non-negative integers n.

PREREQUISITES
  • Understanding of mathematical induction
  • Familiarity with differentiation and factorial notation
  • Knowledge of polynomial functions, specifically $(x^2 - 1)^n$
