Question

Plot the complex number?

Plot the complex number.

−5√3 − 5i

Answer 1

Every complex number `x + yi` has a real part, denoted `x`, and an imaginary part, denoted `y`. Since there are only two parts to any complex number, these parts can be represented on a 2-D Cartesian grid.

It has been agreed that the real part, `x`, is plotted along the horizontal axis, while the imaginary part, `y`, gets plotted along the vertical axis.

For the given complex number, `z= –5sqrt3 - 5i`, we have `x = –5sqrt3` and `y=–5`. The location of this point in the complex plane is thus `5sqrt3` units left and `5` units down from the origin.
graph{(x+5sqrt(3))^2+(y+5)^2=0.02 [-10, 10, -8, 2]}
