Derivative power rule and exponeents
Web6. Derivative of the Exponential Function. by M. Bourne. The derivative of e x is quite remarkable. The expression for the derivative is the same as the expression that we started with; that is, e x! `(d(e^x))/(dx)=e^x` What does this mean? It means the slope is the same as the function value (the y-value) for all points on the graph. WebFeb 15, 2024 · The power rule is used to find the slope of polynomial functions and any other function that contains an exponent with a real number. In other words, it helps to take the derivative of a variable raised to a power (exponent). The Steps All we have to do is: Move the exponent down in front of the variable. Multiply it by the coefficient.
