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

Jan 18, 2018

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
$| z | = | - 4 + i 4 |$

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,

$| Z | = | x + i y |$
$| Z | = \sqrt{{x}^{2} + {y}^{2}}$

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