NettetINTEGRATING FACTORS Sometimes a given differential equation is not exact , but can be made exact by multiplying it by some suitable factor , called the integrating factor (I.F.) . For example , consider the differential equation —ydx+xdy=O Here M = —y and N = x so that — I and ôx Hence the equation is not exact . Nettetwe ﬁrst ﬁnd the integrating factor I = e R P dx = e R 3 x dx now Z 3 x dx = 3lnx = lnx3 hence I = elnx3 = x3. Then we multiply the diﬀerential equation by I to get x3 dy dx +3x2y = ex so integrating both sides we have x3y = ex +c where c is a constant. Thus the general solution is y = ex +c x3. Example
