<p>Hey I was wondering whether it would be better to begin my freshman year with Math 1910 or Math 1920...I have a 4 on AP Calc AB and a 4 on BC as well. If I use my credits and begin at Math 1920 would I have a hard time understanding the course? Do you recommend taking Math 1910 and then 1920? Please help</p>
<p>What’s your major? If you’re a math major, I’d skip to 1920. Personally, I’m going to take Cal 1 again just because, even though I took AB Calc this year and did really well. I want the GPA boost, haha. </p>
<p>If I was a math major though, I’d skip it, but I’m not.</p>
<p>MATH 1920 does not really involve much of the stuff supposedly covered in MATH 1910. MATH 1920 is more about vector calculus and geometry. As long as you are decent at integrations you should be fine in MATH 1920. </p>
<p>The important question is why you got a 4 on the AP. If you are confident about your abilities in basic calculus (maybe you just made a few careless errors), you should probably take the credit. But if you’re a bit shaky on your calculus, you may want to stick with MATH 1910.</p>
<p>
</p>
<p>MATH 1910 supposedly is not any easier than MATH 1920. Math 192 was not that hard when I took it, but many of my friends in 191 really struggled. I would not expect a GPA boost from 191 any more than I would from 192.</p>
<p>Right…Calculus in college isnt exactly the same as taught to prepare for AP Calculus. </p>
<p>I feel like in college the focus is more on proofs.</p>
<p>Hmm. I figure Cal 1 would be easier than Cal 2, since I already know most of the stuff from Cal 1. I only need one semester of math anyway, and can’t stand statistics.</p>
<p>I guess GPA boost was the wrong term. Maybe I should refer to it as less new stuff to learn, therefore I can concentrate more on my science courses.</p>
<p>What major are you in ZFanatic? It’s always good to know Statistics…even if you just take the easier CAS Math 100 one.</p>
<p>^^ Spoken like a true ILRie, lol.</p>
<p>Right now I’m leaning towards microbio, but possibly neuro/behavior. PreMed, if that makes any difference.</p>
<p>Why do you ask?</p>
<p>just wondering. with any of those you could benefit from statistics. and no not spoken like a true ILRie…i think all the contract colleges require stats. </p>
<p>especially for research purposes, statistics is always useful.</p>
<p>oh and i believe texas med schools require 2 semesters of math?</p>
<p>
</p>
<p>Well, MATH 191 is basically Calc2 (requires AP Calc BC to place out of it), and MATH192 Calc3. These are engineering math courses, so I don’t know why a non-engineer would ever take these classes (unless maybe that person were a CS major in Arts). </p>
<p>I don’t really know anything about math in Arts and Sciences, which I’m assuming is what you’re thinking about. If you’re actually starting out from Calc1 (I think it’s MATH 1110, not to be mistaken with MATH 1910), you’ll probably have a much easier time because you’ll have learned most of the material in high school.</p>
<p>Haha, yes you are right Tchaikovsky. I failed to look up the courses and just assumed they were Cal 1 and Cal 2. Thanks for correcting me. I will be taking 1110. Haha.</p>
<p>Resurgam, Texas med schools are only 1 semester of Math, thank goodness. Not that I’m terrified of math or anything, but if I only have to go through Cal 1 that means it’s one less hoop to jump through. Not to mention I may be able to take Spanish next spring which would be nice, and get rid of my Foreign Language req. Haha.</p>
<p>skip 1910 and go straight to 1920 for several reasons. </p>
<p>1: it is extremely helpful to get a little ahead in the engineering curriculum since there are a lot of courses you need to take
2: 1920 isn’t any harder than 1910, plus as long as you remember the basics of calculus you’ll be fine, multivariable builds more on calc 1 than calc 2, and 1910 is mostly calc 2
3: Actually, except for the very end, I’d say the material covered in 1910 is harder than in 1920, you don’t want to have to do those area and volume integrals with one independent variable again, in 1920 you’ll learn how to do them with two and three independent variables which is much better, plus power series and taylor series are annoying, you’ll see power series again in diffy q, but you don’t really need to remember anything about them. Fourier series are where its at, but those aren’t in 1910 or 1920, so you want to get to those sooner by skipping 1910 
4: Even though you already know the material 1910 might have crazy difficult tests making your previous knowledge not helpful as only the brilliant kids will do well on them whether or not they’ve seen the material before, even if the tests are easy, there’s no guarantee you’ll learn the material significantly better the second time around and do any better on tests than people who are learning it for the first time(difficulty of all math classes varies from semester to semester, alot), furthermore a large amount of the class has seen it before and made the wrong choice and decided not to skip it, so all these things combine to mean that the fact that you took calc in high school isn’t a big advantage, and math classes are curved fairly low so it could lower your gpa, better to skip it.
5: 1920 is more interesting</p>
<p>Skip as much physics and chem as you can as well for similar reasons.</p>
<p>I skipped 1910 btw. Though I did get a 5 on the BC exam. But yeah skipping 1910 was a great idea imo.</p>
<p>Can someone rank the instructors for Math 1920 in terms of how well they teach and grade?</p>
<p>Skip 1910. It isn’t going to be a GPA booster. Those people who retook it after getting an AP 5 found that they were in the middle of the curve rather than at the top.</p>
<p>I remember seeing a list of all topics in each engineering math class. 1910, 1920, and maybe 2-3 others. Each had about 25 topics under it. Does anyone know where this is?</p>
<p>If I know all but 3-4 of the 1910 topics, should I skip to 1920?</p>
<p>what if i took bc calc on my sophomore yr w/ a 5…?
i do know how to do some simple stuff (like the ones on ap physics…)
yet cant remember a lot on other parts…</p>
<p>Same, except I took BC as a junior [last year] and got a 5. I figure I’ll just take the credit anyways and review my notes/review book over the summer.</p>
<p>Anyone have any opinions on professors who teach MATH 1920? I was reading the blog of an engineering student, and she said that her professor sometimes randomly called a student up to the board to solve a problem during lectures. In which case I might have a problem seeing as how I don’t remember too much from BC…</p>
<p>You don’t need to remember much from BC besides the basics. Remembering Min/max problems might be somewhat useful so you have a better understanding of whats going on when they come up in multivariable, when the first derivative is 0 its either a min or a max. their you go, your all set now.</p>
<p>Actually I’ll teach you how to do min max problems in 1920 using the second derivative test.</p>
<p>critical points are at Fx=0 and Fy=0, this is a logical and, meaning they both have to equal zero for it to be a critical point, not that one of them has to</p>
<p>H = Fxx*Fyy-(Fxy)^2 </p>
<p>if H>0 and Fxx<0 local max
if H>0 and Fxx>0 local min
if H<0 its a saddle point(looks like a saddle so its a min in one direction and a max in an other basically)
if H=0 your ****ed (test is inconclusive)</p>
<p>since you don’t know what a partial derivative is this is sort of meaningless, but they’re really simple. a multivariable function F(x,y)=something has two independent variables x and y which can both change independently. We’re dealing with surfaces rather than the lines you would get from a single variable function. Think of it as a landscape, you plug in an x and y coordinate of where you are on the landscape and then you get a value at that point which is the height you are at when you at those x and y coordinates. Since its a surface not a line it can have a different derivative depending on the direction you go in. the x partial which I wrote as Fx is the derivative in the x direction on our surface, Fy would be the derivative in the y direction on our surface, Fxx is the second x derivative. </p>
<p>To actually evaluate it is really easy, say for an x partial you just treat y like its a constant and take the derivative normally. so if your function is F(x,y) = 3xy^2 + 5x^5y^2 + xsin(y)+x^(3y) Fx would be 3y^2 + 25x^4<em>y^2 +sin(y) + 3y</em>x^(3y-1)</p>
<p>anyway thats my quick less on some 1920 stuff, I hope its clear</p>
