Solving a difficult differential equation

[Juseb3]

in attachment you can see the equation

I'm sorry, I know that if Ed has a solution, but I really need help.

 

[Juseb3]

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!
