Write the order of the differential equation of the family of the following curves : (1).y=Ae^x + B e^( x+c) Share with your friends Share 0 Shruti Tyagi answered this Dear Student, y=Aex+Bex+c --1differentiating w.r.t xdydx=Aex+Becex⇒y'=Aex+Bex+c ⇒y'=y--2differentiating again w.r.t x we gety''=y' ⇒y''=y⇒y''-y=0Hence required equation is y''=Aex+Bex+c Therefore the order of this equation is 2 as we have y''=d2ydx2 Regards, 1 View Full Answer
