I am in Physics this summer and I just posted a question to others on some physics tips more related to breaking down nasty word problems. In my opinion, get your algebra down really well. I just took calculus over the spring semester and I’m very glad I did. Before I took calc I had not had algebra in close to 20 years, so I needed refreshing. The algebra I had in gen chem had helped, but taking calculus was just what I needed to get my math brain back. I’m not taking calc based physics, but the point is not about knowing calculus as it is about knowing basic algebra, having the skills to manipulate formulas, understanding certain math rules, and even just having good calculator skills. The trig stuff I’m dealing with thus far in Physics seems rather straightforward. I think some basic trig videos on SOH CAH TOA will suffice for that. If you are really rusty and can take a formal algebra/calculus course, I think it will really help in physics. You know best what level you’re at, though. Check out the aforementioned Khan Academy videos and see where your understanding is at. Maybe you remember more than you know. Maybe you’re a math genius already and don’t need my suggestions anyway. However, I imagine anyone coming into the physics class I’m currently taking (Physics 120-1st semester of algebra based) would be heading for serious trouble if they did not have a very good handle on their algebra skills. For some excellent videos, lectures and other free materials check out MIT courseware, too. I have found some of their resources/videos helpful and some were just beyond the scope of what I can understand at this point, but worth checking out.
Best of luck! I for one, am not the biggest fan of physics. While I came to really enjoy (and excel in) my calculus course after initial reservations I don’t think I’ll ever grow to love Physics, but it can be made more manageable.
