 Difficult Problems

Here, we show you a step-by-step solved example of choose an option. This solution was automatically generated by our smart calculator:

$cosh\left(-x\right)=cosh\left(x\right)$

Starting from the left-hand side (LHS) of the identity

$\mathrm{cosh}\left(-x\right)$

Since the expression on the left of the equality is too simple, it's not clear how we can proceed to prove the identity from there. Although we know that the identity is true

true
