<p>So because of poor planning and sheer laziness and stupidity, it has been about since i took calc 2. I got an A and really loved the class and teach. Now i am about to sign up for calc 3 and am freaking out because i am looking at my old notes and i have forgotten all the little tricks and intricate details of how to solve problems. I have about 3 months until the class starts, but i don't know if i am going to be completely able to re-teach myself EVERYTHING. please give me advice. I am taking the same professor this upcoming semester for 3 and everybody says he is great at teaching calc 3. Please tell me how different calc 2 and 3 are, and if i am screwed. Good websites for practice will be much appreciated</p>
<p>Calc III is quite a bit different than Calc II. Calc II is essentially all integration, sequences, and series. Calc III moves on to a lot of very different material. The techniques in Calc II are still going to obviously be quite relevant to Calc III, but it won’t be necessary to reteach yourself ALL of the Calc II material. Reviewing some of the more basic techniques of differentiation and integration are obviously going to be a very good idea. Do you need to remaster the methods of integrating a trig substituted function by parts? Probably not. If you’ve got 3 months until the class starts, then you have more than enough time to do a thorough review of the important material. </p>
<p>I had a 1.5 year gap between calc 2 and calc 3 (took the latter in high school, didn’t decide to get back into math for awhile in college). I think you’ll be fine. Brush up on basic integrals/derivatives/sinusoidal functions beforehand or as they come up. For me, stuff started to come back once I started working with it again and I had no problem.</p>
<p>That’s the most likely scenario. A lot of the techniques will come up again, but there’s a good chance that the instructor will briefly review the relevant methods as you encounter them. If not, you can see what methods you’ll need and go back to brush up on them as you encounter them. </p>
