Course: Calculus II
Topic: Transcendental Functions
Subtopic: Hyperbolic Trigonometric Functions

Overview

Trigonometric functions are defined on a triangle. Similarly hyperbolic trig functions are defined on a hyperbola. They can be expressed in terms of exponential functions thus they tie trigonometric functions, exponential functions, and conic sections together. Very cool stuff!

Objectives

By the end of this topic you should know and be prepared to be tested on:
