Question

can anyone help me with y"+y'=2?

Answer 1

Where are you stuck at?

Answer 2

I don't even know how to start!

Answer 3

First solve the related homogenous differential equation:

\[\Large y''+y'=0 \]

Answer 4

How do I solve this homogenous differential equation?

Answer 5

Let \(y=e^{\lambda x}\)

Answer 6

So I assume you haven't done second or higher order differential equations at all yet? Because usually these kind of problems are tackled before inhomogeneous differential equations show up.

Answer 7

no

Answer 8

I saw that this month, but I don't know how to solve this problem. What do I do with this y that you provided?

Answer 9

differentiate it and then plug it back into your DE, solve for \(\lambda\)

Answer 10

You can use method of undetermined coefficients.
