There are six derivative rules to evaluate the differentiation of the hyperbolic functions in differential calculus. So, learn every derivative formula of hyperbolic functions with mathematical proofs.
$\dfrac{d}{dx}{\,\sinh{x}} \,=\, \cosh{x}$
$\dfrac{d}{dx}{\,\cosh{x}} \,=\, \sinh{x}$
$\dfrac{d}{dx}{\,\tanh{x}} \,=\, \operatorname{sech}^2{x}$
$\dfrac{d}{dx}{\,\coth{x}} \,=\, -\operatorname{csch}^2{x}$
$\dfrac{d}{dx}{\,\operatorname{sech}{x}} \,=\, -\operatorname{sech}{x}\tanh{x}$
$\dfrac{d}{dx}{\,\operatorname{csch}{x}} \,=\, -\operatorname{csch}{x}\coth{x}$
