If you look around, you can find this worked out in a DE book or on line.

Here's another guy from Brazil that posted exactly the same question 2 minutes after you did. He received a (great!) reply.

See Conduction of Heat. - Dec 24th 2009, 04:15 AMgalactus
Zill's Differential Equations with Boundary Problems has this problem outlined. Except, they use k instead of .

That is all I meant. This is a common DE problem and can be found. - Dec 24th 2009, 07:41 AMarbolis
Maybe TPH did it also... "better than the book". (Happy)

See http://www.mathhelpforum.com/math-he...-equation.html. This thread is worth to be a sticky one I believe.
