I have this problem
I know that we can write the initial value problem as
$\frac{dy}{dt} = 5 - \frac{3y}{100+2t},\quad y(0)=50$ but how do i solve this?
i was doing...
$p(t)=e^{\large\int \frac{3}{100+2t}dt}=e^{\frac{3}{2}\ln(100+2t)}$
but what else should be doing?
also do you know a site where I can read more examples about cisterns?
