partial derivative question
Say I'm given a function
$u(x/r, 1/r)$
the function u itself is not defined.
when i take a partial derivative with respect to x, do i just write it as
$u_x(x/r, 1/r)$
or is there a chain rule that i... | {"url":"http://mathhelpforum.com/calculus/86342-partial-derivative-question.html","timestamp":"2014-04-16T05:15:03Z","content_type":null,"content_length":"34926","record_id":"<urn:uuid:95e60e84-07ba-46d6-86f2-9198cef9efba>","cc-path":"CC-MAIN-2014-15/segments/1397609521512.15/warc/CC-MAIN-20140416005201-00235-ip-10-147... |

If XX+YY=ZYZ, what are the values for X, Y and Z?
If XX+YY=ZYZ, what are the values for X, Y and Z?
Since the result for X + Y in the ones column is not the same as the X + Y for the tens column, there must be a "carry", so X + Y = 10 or more. But X + Y cannot equal 10 itself, since then Z = 0, and
