Question

How do you plot `-4+4i` and find its absolute value?

Answer 1

In the Argand plane, the real axis is the x-axis and the imaginary axis is the y-axis. Do you get the point?

For its absolute value,
i.e
`|z| = |-4 +i4|`

Which is the distance of this point in the Argand plane from the origin.

for calculating the absolute value of any imaginary point Z = x+iy,

`|Z| = |x+iy|`
`|Z| = sqrt(x^2 + y^2)`

Use the above concepts and find the absolute value of the above imaginary point on your own.
