Question

How do you plot `4i` on the complex plane?

Answer 1

`4i` is represented by the point `(0,4)` on the complex plane

Explanation:

Complex nmbers consist of Real part and an Imaginary part in the form: `z= (a + bi)` `{a,b} in RR`

The complex plane is simply an `xy` plane where the `x`-axis represents the Real coordinate (`a`) and the `y`-axis represents the Imaginary coordinate (`b`).

In this example: `z=4i -> a=0` and `b=4`

Therefore `4i` is represented on the complex plane by the point `(0,4)`
