| | + | *This function is used to obtain the COS value of 'x' in Degrees.<br/> |
| | + | *It is the reciprocal of SEC function i.e,'''COS(x)''' = '''1 / SEC(x)'''.<br/> |
| | + | *In a right angled triangle '''COS(x) = Adjacent side / Hypotenuse'''.<br/> |
| | + | *To obtain the value in Radians multiply with PI()/180 or use COS function COS(X) |
| | + | *DSEC returns NaN if 'x' is not real |
| | + | The angle can be a single value or any complex array of values. |
| | | | |
| − | where
| + | The following example shows how DSEC is applied to an array of numbers containing numbers 1..10. |
| | + | *Type =1..10@DCOS in Calci |
| | + | *Type =1..10@DCOS or 1..10@DCOS in ZOS |
