Exponential and logarithmic functions

Learn about logarithms, which are the inverses of exponents. Use logarithms to solve various equations. Then analyze both logarithmic and exponential functions and their graphs.

Learn about a very special constant in math that has a pivotal role in the world of exponential and logarithmic function, the constant e.

Learn how to rewrite any logarithmic expression in a different base. For example, rewrite log_2(3) as ln(3)/ln(2). This is very helpful for evaluating logarithms with a calculator, which only evaluates base-10 and base-e logarithms.

Learn how to solve equations that contain logarithmic expressions. For example, solve log(x)+log(3)=log(7).
