Derivative power rule proof
WebJun 14, 2024 · One typical approach is to first define the logarithm and exponential function, prove a bunch of their properties, and AFTER THAT DEFINE $x^y = e^ {y \log (x)}$. Then you can prove that \begin {equation} \dfrac {d} {dx} (x^y) = y \cdot x^ {y-1} \end {equation} Web10. I'm looking for a straight forward proof using the definition of a derivative applied to the exponential function and substitution of one of the limit definitions of e, starting with. e = …

Instead, we're going to have to start with the definition of the derivative:
WebThe power rule for derivatives is that if the original function is xn, then the derivative of that function is nxn−1. To prove this, you use the limit definition of derivatives as h approaches 0 into the function f (x+h)−f (x)h, which is equal to (x+h)n−xnh. If you apply the Binomial Theorem to (x+h)n, you get xn+nxn−1h+…, and the xn terms cancel!
