CSec

Returns the secant of a complex number, one over the cosine.

Syntax

CSec( byref z as Complex ) as Complex

Notes

• CReciprocal( CCos( z ) ). It is infinite where the cosine is zero, and this returns a large finite number rather than an exact infinity because the cosine there is merely tiny, not zero.
• One of the six reciprocal trigonometric functions AfxNova supplies and .NET does not.

Examples

#import "std/numeric"
using numeric

dim as Complex z = CSet( 0.5, 0.25 )

print CToString( CSec( z ) )                 '' 1.085358604751614+0.14522062866143562i
print CToString( CReciprocal( CCos( z ) ) )  '' 1.085358604751614+0.14522062866143562i   -- the same thing
