WebNov 24, 2024 · The function exp (ix) is periodic in x, with period 2*pi. The np.exp () function is able to handle complex arguments; however, it starts incurring errors as the size of the argument increases; i.e, the expression. np.exp (1) - np.exp (1+2*np.pi*x*1j) is not zero for integer x, and the deviation from zero increases as x increases. WebJan 2, 2024 · The absolute value of a complex number is the same as its magnitude. It is the distance from the origin to the point: z = √a2 + b2. See Example 8.5.2 and Example 8.5.3. To write complex numbers in polar form, we use the formulas x=r \cos \theta, y=r \sin \theta, and r=\sqrt {x^2+y^2}.

This formula can be interpreted as saying that the function e is a unit complex number, i.e., it traces out the unit circle in the complex plane as φ ranges through the real numbers. Here φ is the angle that a line connecting the origin with a point on the unit circle makes with the positive real axis, measured counterclockwise and in radians.
