Definition 4.11.1 The hyperbolic cosine is the function coshx=ex+e−x2, and the hyperbolic sine is the function sinhx=ex−e−x2.
What is sinh and cosh on calculator?
Hyperbolic trigonometric functions
The position on the unit hyperbola X2 – Y2 = 1 is defined by the point (COSH(Z),SINH(Z)), where COSH is the hyperbolic cosine and SINH is the hyperbolic sine.
How do you differentiate cosh and sinh?
sinh x = e x − e − x 2 and cosh x = e x + e − x 2 . sinh x = e x − e − x 2 and cosh x = e x + e − x 2 . The other hyperbolic functions are then defined in terms of sinh x and. cosh x .
