Understanding the Power Rule of Differentiation

The video tutorial provides a detailed proof of the power rule of differentiation, which states that the derivative of x raised to the power of n is n times x raised to the power of n minus 1. The proof utilizes the binomial theorem to expand expressions and evaluate combinations to determine coefficients. The tutorial walks through the process of simplifying the expression using limits, ultimately proving the power rule. This rule is a fundamental concept in differential calculus and is widely used.

What is the power rule of differentiation?

• The derivative of x^n with respect to x is n * x^(n-1).

• The derivative of x^n with respect to x is x^n.

• The derivative of x^n with respect to x is n * x^n.

• The derivative of x^n with respect to x is n^x.
