Express the Complex Number -1-i in polar form.

how is complex no expressed in polar form?
what is polar form of complex no?
Please help

• Mathematics -

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.

Convert the complex no. In polar form : 1-i rcosΘ =1 rsinΘ=-1 r=√a2+b2 r=√(1)2+(-1)2 r=√2 TanΘ=b/a =1/-1 =-1 After all this what i have to do to find out value of Θ?
