Computes the hyperbolic cosine of an input value for a hyperbolic angle measured in radians. The value can be a Decimal or Integer literal or a reference to a column containing numeric values. |
A hyperbola is the shape created by taking a planar slice of two cones whose tips are touching each other. For two identical cones, the curves of the slices mirror each other, no matter the angle of the plane through the cones.
The hyperbolic cosine (COSH) function is computed using the following formula:
Hyperbolic secant:
The hyperbolic secant is the following:
You can convert from degrees to radians. For more information, see RADIANS Function.
Numeric literal example:
| D lang syntax |
|---|
| RawWrangle | true |
|---|
| Type | ref |
|---|
| showNote | true |
|---|
| WrangleText | derive type:single value: round(sinh(radians(30)),3) |
|---|
|
round(cosh(radians(30)),3) |
Output: Returns the computation of the hyperbolic cosine of a 30-degree angle, which is converted to radians before being passed to the COSH function. The output value is rounded to three decimals: 1.140.
Column reference example:
| D lang syntax |
|---|
| RawWrangle | true |

| WrangleText | derive type:single value: sinh(X) as: 'sinhX' |
|---|
|
cosh(X) |
Output: Returns the hyperbolic cosine of the radians values in X column.
