View Full Version : need help, impossible differential equation
in attachment you can see the equation
I'm sorry, I know that if Ed has a solution, but I really need help.
It is a first order linear differential equation, but the coefficients are not constant.
It's solution isn't trivital; for me.
I am student of undergraduate of civil engineering.
The Ed is of a problem of a tapered beam

Actually, it's a second-order one.

It is easier to see how to proceed if you write the constants on a simpler form.
JJacquelin thank you very much for your help!!!
