Cosh Calculator
Cosh. Example: Value: 1 number gives 1.54308063482 number. Dimensionless real input bounded to -10..10; these are hyperbolic functions, not angular trigonometric functions. Only this original stated job is proposed, not full historical source coverage. Input domains and output unit must be visible.
Dimensionless real input bounded to -10..10; these are hyperbolic functions, not angular trigonometric functions. Only this original stated job is proposed, not full historical source coverage. Input domains and output unit must be visible. Derivation: Define sinh=(e^x-e^-x)/2, cosh=(e^x+e^-x)/2, tanh=sinh/cosh.
Accepted inputs: Value: -10 to 10 number.
How the calculation works
cosh(x) via positive and negative exponentials
Worked example
With value 1 number, cosh is 1.543080635 number.
