Python – cmath.rect() method
cmath is a Python built-in module that is used for complex number mathematics. cmath module has a method rect() that is used to convert polar coordinate into rectangular form.
Syntax: cmath.rect(r, phi)
Parameter: It take two arguments. First argument r, denotes the modulus of the complex number and the second argument denotes the phase. Both arguments are required. None is optional.
Return: Returns a complex number Z whose modulus is r and phase is phi.
Note: r * (math.cos(phi) + math.sin(phi)*1j) is equivalent to this method.
Example 2: In this example modulus is taken as zero.
Example 3: In this example phase is taken as zero
