I really need help with this homework problem, the topic is differential equations: Solve the D.E. dy/dx = ( x - y - 1 ) / ( x + y + 3 ), by finding h and k so that the substitutions x = u + h and y = v + k transform it into a homogeneous equation dv / du = ( u - v ) / ( u + v )
I do remember solving this, not sure whether I have the solution now.
The solution is... I dunno.

That was like a zillion years ago, lol.
YESS YESS I GOT IT!!!!!
let me see if i still have my ODE notes somewhere.... man I'll find them later
Anyway the answer is...
Good job! That probably is the right answer.. Someone give him a medal
Thank goodness! That means that my senior year of high school was not a complete waste of time!
That makes me wanna revise all the awesome math & physics that i learnt these last few years. Thanks, Bahrom, thank you..
