The derivative of cosh, also known as the hyperbolic cosine function, is a fundamental concept in calculus and mathematics. It is used to describe the rate of change of the hyperbolic cosine function with respect to its input. In this article, we will explore the derivative of cosh, its properties, and how it can be used to simplify complex math problems.

Hyperbolic functions are a set of mathematical functions that are similar to trigonometric functions, but are defined using the hyperbola instead of the circle. The hyperbolic cosine function, denoted as cosh(x), is defined as the average of the exponential function e^x and e^-x. The formula for cosh(x) is:

cosh(x) = (e^x + e^-x) / 2

Derivative of Cosh

The derivative of cosh(x) is denoted as cosh’(x) or d(cosh(x))/dx. Using the definition of cosh(x), we can find its derivative using the chain rule and the fact that the derivative of e^x is e^x. The derivative of cosh(x) is:

cosh'(x) = sinh(x) = (e^x - e^-x) / 2

where sinh(x) is the hyperbolic sine function. This result shows that the derivative of cosh(x) is equal to the hyperbolic sine function.
