Hi all, just a problem I'm having trouble with - thanks
1) consider the differential equation dU/dT = 1(1-U) for t greater than or equal to 0 to infinity.
Using the method of separation of variables show that the general solution of the differential equation is
U(t) = e^t / (A + e^t)
where A is an arbitrary constant.
My attempt: I trouble the 1(1-U) over with the dU and using partial fractions solved for log |U| + log |1-U| C(1) = t + C(2)
This is as far as i got, please help!
