Hyperbolic Functions

Hyperbolic functions are a set of functions that are analogous to the trigonometric functions. They are defined in terms of the exponential function, and they have a number of properties that are similar to the properties of the trigonometric functions. Hyperbolic functions are used in a variety of applications, including calculus, physics, and engineering.

Historical Perspective and Different Notations

The hyperbolic functions were first introduced by Vincenzo Riccati in 1762 in order to simplify calculations with natural logarithms. The standard notations for the six hyperbolic functions in common use are:

• sinh(x) = (e^x - e^-x) / 2
• cosh(x) = (e^x + e^-x) / 2
• tanh(x) = sinh(x) / cosh(x) = (e^x - e^-x) / (e^x + e^-x)
• csch(x) = 1 / sinh(x) = 2 / (e^x - e^-x)
• sech(x) = 1 / cosh(x) = 2 / (e^x + e^-x)
• coth(x) = 1 / tanh(x) = (e^x + e^-x) / (e^x - e^-x)

Applications of Hyperbolic Functions

Hyperbolic functions have a large number of applications in science and engineering, and they appear in a variety of equations to describe the behavior of certain phenomena. These include:

• Electrical engineering: The hyperbolic sine function is used to describe the response of a capacitor to a voltage step.
• Mechanical engineering: The hyperbolic cosine function is used to describe the shape of a hanging chain.
• Physics: The hyperbolic tangent function is used to describe the velocity of an object in special relativity.
• Statistics: Hyperbolic functions are used in the distribution of many statistical functions.
• Finance: Hyperbolic functions are used to model interest rates and bond prices.
