2.11.3 The Remaining Four Hyperbolic Functions and their Derivatives

In this video, we define the hyperbolic functions, and focus on the derivatives of the remaining four hyperbolic functions and their derivatives.
In all but one case, we derive the derivative formulas using the quotient rule or the chain rule, and then we explore the functions graphically by looking at the original function, its derivative, and representative tangent lines on Desmos.com.
