Convert a Complex Number to Polar Form Description Obtain the polar form of a complex number . Polar form is where a complex number is denoted by the length (otherwise known as the magnitude, absolute value, or modulus) and the angle of its vector (usually denoted by an angle symbol that looks like this: ∠).. To use the map analogy, polar notation for the vector from New York City to San Diego would be something like “2400 miles, southwest.” A polar form uses the magnitude of the number as the length of line and the angle at which a number extends.
