this the figure which will led you understand this

See here z represent's complex number......

Answer 4

x and y represents lenght p has covered on x axis and on y axis

I'm still lost, how would -2 become something like that?

Answer 6

-2 can become like that if the imaginary term of a complex term gets kicked off
I mean it becomes zero

Did you get my point. If you draw this complex number
-2
on graph then it will show only it's x coordinate

Answer 8

:) Ah I decently understand this now! Thanks :)
