Express the Complex Number -1-i in polar form.
how is complex no expressed in polar form?
what is polar form of complex no?
plot the number as a point in the x-y (real-imaginary) plane.
-1-i corresponds to (-1,-1)
That point is a distance of √2 from (0,0), and at an angle of 225° measured counterclockwise from the positive x-axis. In other words, (√2,5π/4)
The very basic nature of your question would indicate that you haven't studied the material much yet. Take a few minutes to go over it and understand the examples which are surely there.
