e following is not a D.E.? -(z)=0 of the D.E. xdy + ydx = 0 is B. x² + y² = C hose solution is y = Cx is dy B. dx = xy I C. y A sinx + Bc. D. L di /dt + Ri= C. xy = C C. dy dx y x arbitrary constants are in the general solution of the D.E. y" B. 2 C. 3 y = Ce* is a solution of the D.E. dy + y = 0. dx
