DCOSEC(Number)

• is the angle in degrees.
• DCOSEC(),returns the double-precision cosecant of the given angle

COSEC can be used if the angle is in Radians.
The angle can be a single value or any complex array of values.
For example DCOSEC(1..100) can give an array of the results, which is the COSECANT value for each of the elements in the array. The array could be of any values either '+' or '-' like 1..5@DCOSEC or (-5)..(-1)@DCOSEC.

## Description

• This function is used to obtain the Cosecant value of any Number in degrees.
• It is the reciprocal of SIN function i.e, COSEC(x) = 1 / SIN(x)
• In a right angled triangle COSEC(x) = Hypotenuse / Opposite side.
• To obtain the value in Radians multiply with PI()/180 or use COSEC function COSEC(X)
• DCOSEC returns NaN if 'x' is not real

The following example shows how DCOSEC is applied to an array of numbers containing angles 1..10.

• Type =1..10@DCOSEC in Calci
• Type =1..10@DCOSEC or 1..10@DCOSEC in ZOS
