Assignment 6: Finding Derivatives of Inverse Hyperbolic Functions

In this assignment, we will be finding the derivatives of two functions that involve inverse hyperbolic functions. The inverse hyperbolic functions are a set of functions that are the inverse of the hyperbolic functions. They are used to solve equations that involve hyperbolic functions and are an essential part of calculus.

Derivative of Inverse Hyperbolic Coth

The first function we will be finding the derivative of is:

y = (1-t) \operatorname{coth}^{-1} \sqrt{t}

To find the derivative of this function, we will use the chain rule and the fact that the derivative of the inverse hyperbolic coth function is:

\frac{d}{dx} \operatorname{coth}^{-1} x = \frac{1}{1-x^2}

We will also need to use the fact that the derivative of the square root function is:

\frac{d}{dx} \sqrt{x} = \frac{1}{2\sqrt{x}}

Using the chain rule, we can find the derivative of the function as follows:

\frac{dy}{dt} = \frac{d}{dt} (1-t) \operatorname{coth}^{-1} \sqrt{t}

= (1-t) \frac{d}{dt} \operatorname{coth}^{-1} \sqrt{t} + \operatorname{coth}^{-1} \sqrt{t} \frac{d}{dt} (1-t)

= (1-t) \frac{1}{1-(\sqrt{t})^2} \frac{d}{dt} \sqrt{t} + \operatorname{coth}^{-1} \sqrt{t} (-1)

= (1-t) \frac{1}{1-t} \frac{1}{2\sqrt{t}} + \operatorname{coth}^{-1} \sqrt{t} (-1)

= \frac{1}{2\sqrt{t}} + \operatorname{coth}^{-1} \sqrt{t} (-1)

Simplifying the expression, we get:

\frac{dy}{dt} = \frac{1}{2\sqrt{t}} - \operatorname{coth}^{-1} \sqrt{t}

Derivative of Inverse Hyperbolic Coth with t^2

The second function we will be finding the derivative of is:

y = \left(1-t^2\right) \operatorname{coth}^{-1} t

To find the derivative of this function, we will use the chain rule and the fact that the derivative of the inverse hyperbolic coth function is:

\frac{d}{dx} \operatorname{coth}^{-1} x = \frac{1}{1-x^2}

We will also need to use the fact that the derivative of the square function is:

\frac{d}{dx} x^2 = 2x

Using the chain rule, we can find the derivative of the function as follows:

\frac{dy}{dt} = \frac{d}{dt} \left(1-t^2\right) \operatorname{coth}^{-1} t

= \left(1-t^2\right) \frac{d}{dt} \operatorname{coth}^{-1} t + \operatorname{coth}^{-1} t \frac{d}{dt} \left(1-t^2\right)

= \left(1-t^2\right) \frac{1}{1-t^2} \frac{d}{dt} t + \operatorname{coth}^{-1} t (-2t)

= \frac{1}{1-t^2} + \operatorname{coth}^{-1} t (-2t)

Simplifying the expression, we get:

\frac{dy}{dt} = \frac{1}{1-t^2} - 2t \operatorname{coth}^{-1} t

In this assignment, we found the derivatives of two functions that involve inverse hyperbolic functions. The first function was:

y = (1-t) \operatorname{coth}^{-1} \sqrt{t}

The derivative of this function is:

\frac{dy}{dt} = \frac{1}{2\sqrt{t}} - \operatorname{coth}^{-1} \sqrt{t}

The second function was:

y = \left(1-t^2\right) \operatorname{coth}^{-1} t

The derivative of this function is:

\frac{dy}{dt} = \frac{1}{1-t^2} - 2t \operatorname{coth}^{-1} t

These derivatives can be used to solve problems that involve inverse hyperbolic functions and are an essential part of calculus.
