Title: what is The COSH function ?
Post by: beingchinmay on 10-17-2016, 05:13:55
The COSH trigonometric function returns the hyperbolic cosine of the specified number. The specification for the COSH function is:

FUNCTION COSH (n NUMBER) RETURN NUMBER;

If n is a real number and i = −1 (the imaginary square root of −1), then the relationship between COS and COSH can be expressed as follows:

COS (i * n) = COSH (h)

COSH function:
In the C Programming Language, the cosh function returns the hyperbolic cosine of x.
Syntax:
double cosh(double x);

It is nothing but The mathematical hyperbolic cosine function.
Return the hyperbolic cosine of different numbers:
Example:
SELECT COSH(0)
Output:1.00

In mathematics, hyperbolic functions are analogs of the ordinary trigonometric functions defined for the hyperbola rather than on the circle: just as the points (cos t, sin t) form a circle with a unit radius, the points (cosh t, sinh t) form the right half of the equilateral hyperbola.
