I have an assignment due on monday and I am having trouble. It deals with first order differential equations. I have a grasp of the methods, but am having trouble with algebraic manipulation to get the problems into the right form, at least that is where I think my problem lies. If anyone could help I would appreciate it. Even if you could just give me a hint (like think about completing the square) that would be nice.
I solved the first two problems already.
The assignment is attached in a pdf.
Thank you for that last tip. I substituted the v in, but I have to say I am stuck again. I have no idea how to solve the resulting equation. I don't think it can be an exact question and I can't get it into linear form to find an integrating factor. The variables don't seem separable either. I dunno what to do. I multiplied the right side by v^2/v^2 but am still stuck trying to figure out waht to do.
