Hey Bprp could you make a video on how to solve an ordinary Nonhomogenous differential equation using power series I’ve been trying to prove that it can be done with the ODE y”+2y’+y=e^t because I already know that the answer is c1e^-t +c2te^-t +e^t/4 I just want a clear explanaion on how to solve using power series, and who better than you!

can you please show that Lim x->0 ln(x) = -infinity
by the epsilon delta definition
thank! :)
