Calling Sequence

Parameters

Description

Examples

Calling Sequence

polar(z)

polar(r, t)

Parameters

z

-

expression

r

-

expression, understood to be real

t

-

expression, understood to be real

Description

• 

The polar(z) calling sequence converts the complex-valued expression z to its representation in polar coordinates.

• 

The expression is represented as polar(r, t) where r is the modulus and t is the argument of the complex value of the expression.

• 

This function can also be invoked as a convert function: convert(z, polar).  See convert/polar.
