1) The solution of diffrential equation dy/dx = 1+ y 2 / 1+ x 2 is a) 1+ xy + c (y-x) = 0 b) x+y = c (1-xy) c) y-x = c (1+xy) ) 1+ xy = c (x+y) 2) y = x/x+1 is the solution of the diffrential equation a) y 2 (dy/dx) =x 2 b) x 2 (dy/dx) = y 2 c) y (dy/dx) = x d) x (dy/dx) = y


1)The solution of diffrential equation
    dy/dx = 1+y2/ 1+x2 is
 
      a) 1+xy + c (y-x) = 0        b) x+y = c (1-xy)
      
     c) y-x = c (1+xy)               ) 1+ xy = c (x+y)
 
    2) y = x/x+1 is the solution of the diffrential equation
       
      a)  y2   (dy/dx) =x2         b)     x2 (dy/dx) = y2
 
c)  y (dy/dx) = x          d)    x  (dy/dx) = y
