<p>Dr. Pounds,</p>

<p>Question 2b of your portion of the homework asks for us to
compute imaginary quantities. Would you like for our answers
to be expressed in polar or normal coordinate notation, or
does it matter which we use?</p>

It would be nice if all the final results were in the form <img
style="vertical-align: middle"
src="cid:part1.06020002.08010307@mercer.edu" alt="$a \pm bi$">.
However, in some cases the problems are MUCH easier if you convert
them to polar coordinates and even easier if you express them to
Euler's represenation (p. 236-237 of Steiner). Once in Eulers
representation the math almost becomes trivial. It is also
straightforward to take all of the results that were calculated in
the Euler representation and convert them back to <img
style="vertical-align: middle"
src="cid:part1.06020002.08010307@mercer.edu" alt="$a \pm bi$">. <br>
