Power rule - Wikipedia
网页In calculus, the power rule is used to differentiate functions of the form () =, whenever is a real number. Since differentiation is a linear operation on the space of differentiable functions, polynomials can also be differentiated using this rule.
Power Rule – Derivation, Explanation, and Example - The Story …
网页The power rule helps us find the derivative of functions and expressions raised to a power. We’ll explore how this particular derivative rule was derived and understand why we need to establish a power rule for expressions with a higher power.
Power Rule - Math is Fun
网页Power Rule. Power means exponent, such as the 2 in x 2. The Power Rule, one of the most commonly used derivative rules, says: The derivative of xn is nx(n−1) Example: What is the derivative of x 2 ? For x 2 we use the Power Rule …
3.1: The Power Rule - Mathematics LibreTexts
网页2020年12月21日 · We start with the derivative of a power function, \( f(x)=x^n\). Here \(n\) is a number of any kind: integer, rational, positive, negative, even irrational, as in \( x^\pi\). We have already computed some simple examples, so the formula should not be a complete surprise: \[{d\over dx}x^n = nx^{n-1}.\] It is not easy to show this is true for any ...
