Dear Professor Taylor,
I was working on the webworks assigned problems
and the answer wasn't correct (answer is below). I was hoping to see what
is wrong because I'm pretty sure the answer is correct.
(x-2)^2+(y-7)^2+(x-3)^2-62
**************************
You were thinking the right thing, but you didn't write what you were thinking: the
(x-3)^2 should be (z-3)^2. (this is a innocent example of how mistakes are made, for
example how little-bitty bugs get in software that cause million dollar software failures)
