Students will learn how to prove identities involving hyperbolic functions. Here are some identities:

\(\sinh\) is odd: \(\sinh -x = -\sinh x\)

Proof: Geeth's Maths Tutorials or The Math Sorcerer

\(\cosh\) is even: \(\cosh -x = \cosh x\)

Proof: Geeth's Maths Tutorials

\(\tanh\) is odd: \(\tanh -x = -\tanh x\)

Proof: Geeth's Maths Tutorials

Sum identity for \(\sinh\): \(\sinh(x + y) = \sinh x\cosh y + \cosh x\sinh y\)
