Chapter 3
Exponential and Logarithmic Functions

In this chapter we will learn about two important functions: the exponential function and the logarithmic function. These functions are special in the way that they are not algebraic, they are transcendental.


John Napier (pictured above) was born on February 1st, 1550 and was the inventor of Logarithmic functions. He started working on them in 1594. The inventor of exponential functions was a man named Jakob Bernoulli. He was born on January 6th, 1655. Both of them impacted the math world by creating two functions that are still used today.
