How to solve or approximate a first order differential equation ?
Posted:

Hello everyone,
I have this first order differential equation:
y'[t] = A (y[t])^2 + B (C  y[t])
where A and B are unknown constants and C is known constant. One condition is y[0]==0
A and B should be determined by fitting a list of {y[i],t[i]} values.
For this reason i would like to approximate my differential equation with a function which I could use to fit the data and find A and B.
I don't know how to do this. Any help is highly appreciated.
Thanks,
