Thankyou! But i still need to study it to convince myself of it totally.

Thanks Ok i think i see that now. But say we factorise x^{3}+3y^{2}x-x=0 and get x=0 If we then then plug that result (x=0) into x^{3}+3y^{2}x-x=0 we get 0^{3}+3y^{2}\times0-0=0 which becomes y^{2}\times0=0 this means the value of y could be anything! How do...

then why does this method not yield all the solutions :(

sorry i am tired i mean: y^{3}+3x^{2}y-y=0 x^{3}+3y^{2}x-x=0 They are not supposed to be differential equations this is just part of the problem.

Hey everyone! Homework Statement This is part of a question on finding minima,maxima and saddle points in multi variable functions. In this section i need to solve the differential equations: y^{3}+3x^{2}y-y [1] x^{3}+3y^{2}x-x [2] Homework Equations --- The Attempt at a...

legendary. Thanks Xaos :)

Thanks for your replies everyone :) You are correct that is the definition of the delta function sorry about that. I still don't understand how he gets that though. @Xaos: I'm sorry I'm not sure i understand you :(

Homework Statement This is an example provided by my lecturer in his notes. He puts practically zero working in. When i work the problem through i do not get the same answer as he does. In this section i have copied the exact text from the problem: Find the Fourier transform of...
