dy/dx= (y^2 1)/x
1. Give the general equation of the curves that satisfy this equation.
2. Show that the straight lines y=1 and y=1 are also solutions
3. Do any of the curves you found in 1) intersect y=1?
My Ans:
1. The general solution i found out to be x^2 + C = (y1)/(y+1), correct?
2. Does that mean y=1 is a solution and y=1 is not because it will have a denominator of zero?
3. The only intersection is at x=0, y=1 , since x can't be 0, there are no curves intersecting y=1
Am i doing anything wrong here?
