How do you find the phase of a complex number in NumPy?

angle() function is used when we want to compute the angle of the complex argument. A complex number is represented by “ x + yi ” where x and y are real number and i= (-1)^1/2 . The angle is calculated by the formula tan-1(x/y).

How do you find the phase angle of a complex number in Python?

The cmath. phase() method returns the phase of a complex number. A complx number can be expressed in terms of its magnitude and angle. This angle is between vector (representing complex number) and positive x-axis is called Phase.

How to use modulus in NumPy?

mod() is another function for doing mathematical operations in numpy.It returns element-wise remainder of division between two array arr1 and arr2 i.e. arr1 % arr2 . It returns 0 when arr2 is 0 and both arr1 and arr2 are (arrays of) integers. Parameters : arr1 : [array_like] Dividend array.

What does NumPy exp do?

exp. Calculate the exponential of all elements in the input array.
