DCOSEC(x)


  • where x is the angle in Radians
  • by default Calci use Radian as angle

COSEC can be used if the angle is in Radians.

Description

  • This function is used to obtain the Cosecant value of 'x' 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 angle can be a single value or any complex array of values.

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

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