Thanks your answer. I can't do these 3 equation at all, if somebody show me the deduction, I think I will understand these types of probems.

1. Move the "-t" to the other side, then you have a first order linear DE. Do you know how to solve with an integrating factor?

2. This is a second order linear constant coefficient nonhomogeneous DE. Can you at least get started by solving the homogeneous equation?

3. With some algebraic manipulation you can separate the variables.

Thank you very much but i never did differential equations. And this is a homework for me. These are the last 3 exercise and i can t do is. Would you have enough time to solve it for me please?
