ABSTRACT
Exponential functions are used in engineering, physics, biology and economics. There are many quantities that grow exponentially; some examples are population, compound interest and charge in a capacitor. With exponential growth, the rate of growth increases as time increases. Understanding and using exponential functions is important in many branches of engineering. The chapter describes exponential functions using a calculator, plot graphs of exponential functions and evaluates Napierian logarithms using a calculator, solve equations involving Napierian logarithms. It explains the many examples of laws of growth and decays in engineering and science perform calculations involving the laws of growth and decay and reduce exponential laws to linear form using log-linear graph paper.
