Calculate the hyperbolic cosine of a number.

`=COSH(number)`

- number - any real number

`COSH(0)`

The COSH function returns the hyperbolic cosine of an argument. In this example, the argument is 0, which returns the x-coordinate 1. Therefore, it will evaluate to 1.

`COSH(a)`

The COSH function returns the hyperbolic cosine of an argument. In this example, the argument is a, which is a variable or a number. This formula will evaluate to the hyperbolic cosine of a.

The COSH function is used to calculate the hyperbolic cosine of a number, which is the cosine of the hyperbolic angle of that number. COSH requires real number arguments to be provided.

- The COSH function returns the x-component of the hyperbolic angle, which is a ray from the origin of the coordinate system that passes through a point on the hyperbola.
- The hyperbolic angle area is equal to one-half the hyperbolic angle.

The COSH function calculates the hyperbolic cosine for a number. The hyperbolic cosine of a number is the cosine of a number expressed as a hyperbolic angle.

The argument for COSH is number. The number argument is any real number.

The number argument is required for the COSH function.

The COSH function can be used to calculate the hyperbolic cosine of a number, expressed as a hyperbolic angle. It can also be used to compare angles in hyperbolic space.

- It can provide insight into the relationships between hyperbolic angles.
- It can help to determine trigonometric relationships in hyperbolic space.
- It can help to visualize the pattern of the hyperbolic angle.
