Calling Sequence

convert( expr, polar )

Parameters

expr

-

(complex) expression

Description

• 

convert/polar converts an expression to its representation in polar coordinates.

• 

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

• 

This function can also be invoked directly as polar(expr).  See polar.
