Help me solve this math problem! 2 hrs until class

[rhinox99]

Can anybody at least give me some hints on how to start doing this?
It's an extra credit problem that I really want to do.

Find the simple closed curve C for which the value of the line integral is a maximum:

(integral sign with a C under it goes here) (y^3 - y)dx - (2x^3)dy

If you know how to solve or at least start it, please give me some help

I just started learning integration by myself, so this is prolly wrong...

But here's my shot at it:


-(dy x^4 )
-------- + dx x y (-1 + y^2 )
2

hmmmm any other ideas everyone?

 

[rhinox99]

2 hours until it's due Can anybody help?

Is anything unclear? I'd be happy to answer questions

ha ha. e.c. or not it is still cheating.

 

[rhinox99]

Asking for help is cheating? How am I ever supposed to learn then?

I gave it my best try already and I'm stumped... not much left to do but ask for help

dy/dx = (y^3-y)/(2x^3)

see if you can take it from there. if not, i'll be back.....maybe....(i hope i'm doing it right).
