Need Help In Math

[shermaine]

Hello,

This is definitely a math question i got from some reference book.
I'm strucked at the beginning of this question. Any one can help me.
It's not a homework. I'm learning too , if not i wont post it on the web.

Q: Solve the 1st order linear differential eqn

(4y-8x(power of 4))dx + xdy =0

Q: Find general solution to the differential eqn

dy/dx= [3 x(power 2) ylny] / [2y - X (power 3) - x(power 3) ln y]

[/code]

looks like homework... :shock:

I agree looks like homework. Nonetheless, why dont you make an attempt to solve the problem and show us your work. Then we can help you. As you become better, you will be able to look at most diff eqns and know the general form of the solution without picking up a pencil. I would begin by identifying what type of diff-e each of these is.

Hello,

I dun even know how to arrange it in order
I'm really strucked....any one can help me in the beginning and i will do the rest and post it in the web.....Pls pls

First, you need to be able to collect the terms and identify what type of diff-e this is. If you cant do that, it is unlikely you are going to solve the rest of the problem.
