A*B DATA: a b c d -1 0 2 3 5 -1 2 -1 0 3 0 2 ..2 .1 .3 .1 EXPRESS YOUR ANSWERIN: 1. RECANGULAR FORM 2. POLAR FORM 3. EXPONENTIAL FORM

Now put yourself in our shoes for a moment. If you were reading a post which was identical to the one you made (which is nothing more than a problem statement) what EVIDENCE could you point to that attempts had been made to solve the problem? There is simply NO evidence that you did a single thing beyond copy-paste. You did not even say, "I am having trouble understanding this problem statement." % Evidence you READ it. "I am stuck on part 2." % Evidence you attempted to understand it. "Here is the code tried. I get this error message..." % Evidence you attempted to do it.

Perhaps I should have posted my attempts for further clarification. My questions are homeworks from a 100 level engineering course for undergrads. I have a PhD in a non science discipline and am interested in learning more about computers, so electively decided to sign up for this course. It's a littile more difficult than I realized for I haven't taken a precalculus like course in over 20 years..... I have contacted an engineer friend of mine and he feels that the question is very dated and a poor example to use. What do you think?
