ODE

(a) Rate of Change of y w.r.t. x which is directly proportional to y
(b) Rate of Change of y w.r.t. x which is directly proportional to the product of y^2 and x
(c) Rate of Change of y w.r.t. x which is inversely proportional to y
(d) Rate of Change of y w.r.t. x which is directly proportional to y^2 and inversely proportional to square root of x
