dP/dt = te^(t+P) ; where P = 1 when t = 0.

I got to the part where:

dP/(e^P) = te^t dt

Found the integral:

-e^(-P) = te^t - e^t + c

Not sure how to find the solution. (we also can't ln a negative).

Have you consdiered substituting the given values for p and t?

Note: Is it "p" or "P". Normally, it's bad form to be switching about. - Apr 14th 2010, 01:37 PMAlphaRock

How did you get C = 0? Please try that again.

It may help to write it as

Hmm... "ln" really isn't a verb. Try not to speak pigeon math. - Apr 14th 2010, 05:59 PMAlphaRock

You seem to be saying that .

Please reconsider, particularly since later you have . You can't have it both ways!

Be more careful.
