Hi all,

I've been away from calculus for about 2-3 years (though in the interm have taken other math like analysis and algebra) and I'm preparing to start a course in ODEs next semester, to be followed next year with more courses on dynamical systems and PDEs. I have basically zero experience with DEs. I want to brush up on some calculus skills before the course starts, but I only have a couple weeks to do so. Any suggestion for areas to focus on?

Thanks,

Brian
