dy/dx= (x^2+y^2-1) / x- y dy/dx=0 implies (x^2+y^2-1) / x- y=0

do i integrate with respect to x?

(x^2+y^2-1) / x- y=0 (x^2+y^2-1)=0
anonymous
  • anonymous
so the critical point would be 0 ?
anonymous
  • anonymous
have u got any values for x and y
anonymous
  • anonymous
no. im really confused
anonymous
  • anonymous
usually dx/dt and dy/dt equals to something in 't'. Have u got something like x=2t , y=1+t etc ???...otherwise you cant really go further than that
anonymous
  • anonymous
everything i wrote at top is the only thing that it gave me
anonymous
  • anonymous
ok then...here is the final word
anonymous
  • anonymous
(x^2+y^2-1)=0 y^2=1- x^2 y= +- sqrt(1- x^2) are the critical points
anonymous

fan me if u liked my try to help u .thanx
