Solve the differential equation by variation of parameters. y" + 3y' + 2y = 1 / 1+ ex y(x) = ???
Added by Dennis M.
Step 1
The complementary solution is the solution to the homogeneous equation: y'' + 3y' + 2y = 0. We can solve this by finding the characteristic equation: r^2 + 3r + 2 = 0. Factoring, we get (r + 1)(r + 2) = 0, so r = -1, -2. Thus, the complementary solution is: y_c(x) Show more…
