Study Guide Overview

This study guide covers derivatives of exponential and logarithmic functions. It includes differentiation of eˣ, eᵏˣ, aeᵏˣ, aˣ, aᵏˣ, ln x, a ln x, and ln kx. The guide provides worked examples, practice questions, and a glossary of key terms like the chain rule and constant multiple rule. Key takeaways emphasize correct application of these rules and properties of logarithms.

#Derivative of the Exponential Function

#Differentiating exe^xex

The function f(x)=exf(x) = e^xf(x)=ex is unique because its rate of change is equal to itself.

f′(x)=exf'(x) = e^xf′(x)=ex

#Differentiating ekxe^{kx}ekx

For the function g(x)=ekxg(x) = e^{kx}g(x)=ekx, its rate of change is proportional to itself.

g′(x)=kekxg'(x) = k e^{kx}g′(x)=kekx

This result is due to the chain rule.

#Differentiating aekxa e^{kx}aekx

For a function with a constant multiple of the exponential, the differentiation fo...
