NAME
cas - trigonometric cosine plus sine
SYNOPSIS
cas(x [,eps])
TYPES
x number (real or complex)
eps 0 < real < 1, defaults to epsilon()
return number
DESCRIPTION
Calculate the trigonometric cosine plus sine of x to a multiple of eps with error less in
absolute value than .75 * eps.
This function is sometimes called cosine and sine, is equivalent to:
cas(x) = cos(x) + sin(x)
EXAMPLE
; print cas(1/2), cas(5/7), cas(42/7)

NAME
cis - Euler's formula
SYNOPSIS
cis(x [,eps])
TYPES
x number (real or complex)
eps 0 < real < 1, defaults to epsilon()
return number
DESCRIPTION
Calculate the Euler's formula value of x to a multiple of eps with error less in
absolute value than .75 * eps.
This function is sometimes called cosine and sine, is equivalent to:
cis(x) = cos(x) + 1i*sin(x)
cis(x) = exp(1i * x)
