Doing well in multivariable calc

<p>i'm taking multivariable calc this year and this is really probably the most challenging math class i've taken... i breezed through calc bc and all of the previous classes with minimal homework... now i'm actually doing homework and i'm not doing all that well (C on the last test!). i really need a good grade in this class (just to prove to myself that i'm not washed up), any tips? ways to study? helpful resources? thanks in advance guys.</p>

<p>MV Calc is just an extension of Calculus BC...your BC class must have not been very rigorous with the work. In many cases MV Calc comes out of the same book as BC Calc.</p>

<p>yeah, i don't think my calc bc was very rigorous... so what do i do?</p>

<p>i wouldn't say this is really "impossible," but it's actually pretty challenging now... so yeah, i'm wondering what i ought to do? just do mass homework probs?</p>

<p>Weird, I found multi to not be that bad, but a lot of it depends on how the class I guess. A good teacher can really make a difference. Is there a specific topic or concept you're having trouble with?</p>

<p>What's helped me a lot is just doing tons of problems from the text. I usually take a lot of notes during lecture, skim the proofs in the text, do some examples, and then a few textbook problems. I keep my calc book in the kitchen too, so if I'm eating breakfast or something I'll do a couple. It helps to spread out the homework during the day and I think makes it easier to retain the info...</p>

<p>P.S. I found some notes that are pretty helpful online. If you Google "Paul's Online Math Notes" it should come up as the first result.</p>

<p>Thanks guys :).</p>

<p>I doubt you did well in Calculus BC if you're not doing well now. It's all built up. If you don't have the support, you'll come crashing down.</p>

<p>Calc BC can be kinda lax on the theory, as the AP test doesn't cover much of it. To do well in multivariate calc, you need to know a bit more of the theory. It can also depend a huge amount on how the class is taught and how hard the problems are.</p>

<p>multivariable ... is that calc 3?</p>

<p>When you guys say rigorous, do you mean like real analysis rigor? My calc class isn't rigorous at all. We don't utilize the epsilon/delta limit definition, and hence cannot prove in class any limit theorems. So basically, the calc course is very watered down theoretically and skewed toward the mechanistic side of calc.</p>

<p>dima, Calculus III = Multivariable Calculus</p>

<p>can someone help me solve this problem:</p>

<p>LIM as X goes to
positive infinity:</p>

<p>([sq. rt. of x+1] - [sq. rt. of x-1])X</p>

<hr>

<pre><code> (sq. rt. of Xsquared + 1)
</code></pre>

<p>(a little calc.i fun for you all)</p>

<p>il bandito, yes, rigorous as in proving everything and understanding the proofs. Your calc class probably don't do any delta-epsilon proofs because the AP test doesn't require them, and most calc classes teach for the AP tests.</p>

<p>dude, come on. calc 3 is the easiest math class i've taken so far. of course, so far it's just basics, but seems like a piece of cake in comparison to calc 2</p>
