Python - cmath.rect() method Last Updated : 01 Jun, 2020 Comments Improve Suggest changes Like Article Like Report 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 1: Python3 # Import the Library import cmath # Printing the result print (cmath.rect(3,10)) Output: (-2.517214587229357-1.6320633326681093j) Example 2: In this example modulus is taken as zero. Python3 # Import the Library import cmath # Printing the result print (cmath.rect(0,1)) Output: 0j Example 3: In this example phase is taken as zero Python3 # Import the Library import cmath # Printing the result print (cmath.rect(1,0)) Output: (1+0j) Comment More infoAdvertise with us Next Article Python - cmath.rect() method A aman neekhara Follow Improve Article Tags : Python Python Cmath-library Practice Tags : python Similar Reads Python | cmath.sqrt() method With the help of cmath.sqrt() method, we can find the value of square root any number by passing it to cmath.sqrt() method.
