Answer to Problem 6AYU
Modulus, magnitude.
Explanation of Solution
Given Information:
When a the non-negative number
the _____or _______ of z, and the angle
is the argument of z.
Calculation:
If represents a complex number in polar form, then its distance from the origin
is called its modulus or magnitude and the angle
is called its argument, where
and
.
Therefore,
when a complex number z is written in the polar form the nonnegative number r is the modulus or magnitude of z, and the angle
is the argument of z.

- A 20 foot ladder rests on level ground; its head (top) is against a vertical wall. The bottom of the ladder begins by being 12 feet from the wall but begins moving away at the rate of 0.1 feet per second. At what rate is the top of the ladder slipping down the wall?
