Question

How do you plot the number `-1+i`?

Answer 1

See explanetion.

Explanation:

To plot a complex number `z=a+bi` you just plot a point which `x`-coordinate is the number's real part (here `-1`) and `y`- coordinate is the number's imaginary part (here `1`)

graph{((x+1)^2+(y-1)^2-0.001)=0 [-2.5, 2.5, -2.5,2.5]}
