Cos

concerns

The Cos function returns the value corresponding to the cosine of the passed value.

Notes

The Cos function calculates the ratio of two sides in a right-angled triangle from an angle. The ratio is the length of the side attached to the angle divided by the length of the hypotenuse.

The result ranges from -1 to 1.

In order to convert degrees to radians, the degree must be multiplied by π/180.

Example

Dim Angle As Double, Secans As Double

Angle := 1.3                                                             # define angle in radiant

Secans := 1 / Cos(Angle)                                      # calc the Secans

In this example, the Cos function is used to return the secans of an angle.
