Not sure if I should have put this here or in the homework section but I am simply asking for direction on these problems. I have 5 problems to work on and my biggest problem is identifying what method to use to find the answer. I don't need help answering because it's something I'd like to do myself but have some trouble with as I learn. Don't know how to use the neat forum stuff yet but will learn as I become part of the community slowly. Problems to work on... http://img261.imageshack.us/img261/9066/matwk8.jpg [Broken] Those are the problems and so far I can see... #1 ? #2 is a separable equation correct? #3 ? #4 is substitution and then exact? Already marked that one exact since I did it already. Can't tell which one would follow Bernoulli equation, integrating factor, linear first order. Thank you to anyone who would kindly reply :x Edit: Took a look at the rules again and see that this really should belong in the homework section. I'm very sorry, I'll ask an admin/mod to move it.
