Question

Find Arg z and arg z for the complex number a) (1+i√3)/(-2) b) (1+i)^5

Answer 1

Step-by-step explanation:

Consider above image, argument of a non-zero complex number z is defined as the angle made by the line connecting z to origin with abscissa of the complex plane (in radians).

so

arg(z)= arctan(b/a)

Coming back to your problem z = 1-i

that means arg(z) = arctan(-1/1) = - pi/4
