Hi!

First of all I am Norwegian, and my math-english might not be totally correct.

Okay, I have a problem with a first order separabel differential equation:

I seperate:

Splitting the fraction and differentiate it:

Mr F says: This should be $\displaystyle {\color{red} \frac{1}{A \lambda} \ln \left(\frac{y}{A {\color{blue}-} y}\right) = t + C}$
I now have to put the y on the one side of the equation, but I'm unsure of how to do this. This is as far as i have gotten:

Is there something I am doing wrong in the steps above?

Any help would be greatly appreciated!

Thank you in advance,

Thomas
