# Cosh and sinh relationship

### Hyperbolic Functions

It is known that the hyperbolic sine and cosine are connected by the relationship (tanhx)′=cosh2x−sinh2xcosh2x=1cosh2x=sech2x. Similarly, we can obtain. And similarly, for the hyperbolic sine we write s i n h, for . Now what I claim is that cosh and sinh have the same relationship to this hyperbola as cosine. real values of x by the relation cosh x = (a) By multiplying the expressions for cosh x + sinh x Use the definitions of sinh x and cosh x in terms of exponential.
