Re: [differential equations] stuck on a problem
Maybe you're making mistakes in the arithmetic? I find that it's often really hard to keep track of stuff like -5 - 2*-1, so it could be that you're doing all the hard stuff right. And you can always check stuff with wolframalpha, like dag12 mentioned (you can even put in only 2-3 rows and see what it does with those).
