Question

How do you simplify `abs(-3.6i )`?

Answer 1

`abs(-3.6i) = 3.6`

Explanation:

One way to look at the absolute value is as the distance from the origin (where "distance" is always non-negative).

Since `(-3.6i)` has no Real term we are looking at the distance from `(0,0i)` along the Imaginary Axis to `(0,-3.6i)`

This distance is clearly `3.6` units.
