Is a function of , or are we treating it as constant?
Danny and Prove it
Not sure I understand how you got the last term on the 2nd last line...? Can you clarify. FYI, my procedure is
dy/dx = -1, therefore y=-x+k, du/dx=u/(x+y) therefore .
Not sure what I have done wrong so far...
prove it, the above integration is based on assuming y is constant....not sure of this right
Thanks
