Differentiation of Hyperbolic functions

The derivative of a hyperbolic function with respect to a variable (used as real number of the function) is called differentiation of the hyperbolic function with respect to that variable.


Take $x$ and assume it represents a real number. The six hyperbolic functions are written as $\sinh{x}$, $\cosh{x}$, $\tanh{x}$, $\coth{x}$, $\operatorname{sech}{x}$ and $\operatorname{csch}{x}$ or $\operatorname{cosech}{x}$. The derivative of each hyperbolic function with respect to $x$ is listed here for beginners.


Hyperbolic sine function

$\large \dfrac{d}{dx} \, \sinh{x} \,=\, \cosh{x}$


Hyperbolic cosine function

$\large \dfrac{d}{dx} \, \cosh{x} \,=\, \sinh{x}$


Hyperbolic tangent function

$\large \dfrac{d}{dx}{\, \tanh{x}} \,=\, \operatorname{sech}^2{x}$


Hyperbolic cotangent function

$\large \dfrac{d}{dx} \, \coth x = -\operatorname{csch}^2{x}$


Hyperbolic secant function

$\large \dfrac{d}{dx} \, \operatorname{sech} x = -\operatorname{sech}{x}\tanh{x}$


Hyperbolic cosecant function

$\large \dfrac{d}{dx} \, \operatorname{csch} x = -\operatorname{csch}{x}\coth{x}$

The six differentiation rules of hyperbolic functions are used as formulas in differential calculus mathematics.
