WebTo solve a linear second order differential equation of the form. d 2 ydx 2 + p dydx + qy = 0. where p and q are constants, we must find the roots of the characteristic equation. r 2 + pr + q = 0. There are three cases, depending on the discriminant p 2 - 4q. When it is. positive we get two real roots, and the solution is. y = Ae r 1 x + Be r 2 x
WebSo our one repeated root is 1 plus or minus 0 over 2, or it equals 1/2. And like we learned in the last video, you might just say, oh well, maybe the solution is just y is equal to ce to the 1/2 x. But like we pointed out last … Webi.e. if some of the roots are repeated, then the solution of the form given in Eqn. (7) is not the general solution of Eqn. (5). Recall that if r 1 is a repeated root of the second order linear equation ay00 + by0 + cy = 0, then two solutions are e r 1t and te 2t. For a differential equation of order n, if a root of Z(r) = 0, say r = r 1 has ...
WebRoots separated by an integer. The previous example involved an indicial polynomial with a repeated root, which gives only one solution to the given differential equation. In general, the Frobenius method gives two independent solutions provided that the indicial equation's roots are not separated by an integer (including zero).
