How hard is calculus 3

edited June 2011 in UC Transfers
How hard is the third calculus class exactly? compared to calculus 2? I am having fken nightmares about this class already. I think calc 2 has scarred me for life cuz i tried really hard and had an A until his crazy 40% final. ( I am taking calc 3 with the same teacher I had for calc 2). Will I be studying 24/7 like in calculus 2 and thinking im going crazy at the end?
Will I have to sell my soul to get an A? I really need an A because my major is fken hard and I'm taking this to make up for my B in calc 2 and Ws in calc 1.

Course Description-Multivariabe calculus. Vector valued fuctions, functions of several variables, partial differentiation, multiple integration, change of variables theorem, scalar and vector fields, gradient, divergence, curl, line integral, surface integral, theorems of Green, Stokes and Gauss, applications.

    It's not hard.

    I hear that it is alot easier than calc 2 so u should be ok. What did you struggle with most with in calc 2? Im taking it now and it seems ok... there are just more topics (inverse fns,polar coordinates, differential equations, sequences and series, etc.)

    everything goes 3D.. not too hard..

    If you can pass Calculus 2, you'll have no problem with 3. Calculus 3 is highly conceptual and all the 3-D stuff is actually pretty fun. Calculus 1 was okay, 2 was horrible and 3 was fun.

    Since Calc 3 deals with a lot of 3 dimensional ideas, it can be challenging. Contour Diagramming, triple integrals, vector fields can be a whole new idea and topic to some students. For me both subjects weren't that hard, just a lot of work put into it.

    You'll be fine. Calc 3 is a walk in the park compared to Calc 2.

    Not hijack the thread, but..is Calc 2 hard? I'm taking it right now and seems like the consensus on here is that its quite difficult..

    makes me worried since I'm not a calculus superstar

    My son took Calc 2 in the Fall at CSU Sacramento and is now taking Calc3 in the Spring semester. While my son is a Geology major, most of his Calculus classmates are Engineering majors who after Calc 2 still have to take Calc 3, Linear Algebra and Differential Equations. The consensus among them is that if you survive Calc 2 (Math 31 at Sac State) you are basically home free as far as mathematics courses go.

    Look, I'm not going to let pride get in the way, I finished Multivariable Calculus (which I think you're taking as Calc 3) with a B in the class and overall thought I did very well.

    The first couple of weeks in that class scared the crap out of me; that class took a lot of practice, looking at problems properly, sideways.. upside down? (lol, just kidding). It does get easier as you go on, and after the first few weeks you'll get used to the freaky examples/graphs.

    I'll agree with the sentiment that if you made it through Calc 2, you'll make it through this class. Just keep your head up, study hard, and it'll be ok ^^

    Perhaps it was my teacher that liked to mumble as he stood in front of the examples he'd work out on the board, or it was that damn Stewart book and its .. yea I'm going to use that awful word.. rigorous math problems. In the end, I didn't find the class to be a walk in the park (and at least half of the class dropped).

    So don't expect it to be a walk in the park.

    Of course, this is math/physics land, and the rules say that you have to go "Oh that's SO easy!" when someone freaks out. That's a rule! Remember it ;)

    Calc 3 is pretty heavy on the conceptual side, you will be given theorems Like Stokes and Greenes, that in theory are pretty complicated, but applying them is pretty simple and computations are not hard at all. So basically what im saying depending on how deep your teacher tests your knowledge theorywise opposed to just applying a theorem you dont know the meaning of this class can either be a nightmare or somewhat easy. I go to New Jersey School of Technology and had it last semester and found it challenging but doable. I managed an A, but I am OCD and study non-stop. I also managed an A in Calc 2 and 1. Calc 2 to me was very simple, just harder on the computational side.

    Anyone go to NJIT?

    to add to my last post, you just need to be able to visualize in space and have some sketching skills.

    Well I just started it, and so far it couldn't be easier. My professor says the multi-variable stuff isn't too bad (just multi-variable versions of calc 1 and some weird graphs) and that the Vector stuff is what catches most kids out. I thought calc 2 was pretty easy so hopefully I won't get caught out later this semester, but so far it's been pretty fun haha.

    Easier than Calculus 2, about a little bit harder than calculus 1.
  • rattleheadrattlehead Registered User Posts: 92 Junior Member
    For me, Calc 1 was a breeze, 2 was fairly easy (A's in both), and 3 was the hardest college course I've taken as of yet (got a B). But everyone else seems to say that 3 is much easier than 2, so most likely you'll do fine. If you can pass 2, you can pass 3.

    People say that Calc 2 is hard because it involves sequences and series. Other than that, you're mainly just setting up and solving integrals.

    During the multivariable part of Calculus, that's mainly what you do too. Set up double and triple integrals to find area, volume, and more. The hard part would probably be Vector Calculus, which, in my opinion, is the most rewarding and important part of the class for anyone majoring in physics or engineering. You'll use it a lot studying fluids, electromagnetics, etc. Obviously the difficulty is partly subject to where you take it and with whom, but solving integrals is a lot easier than setting them up to mean something physically, and a lot less interesting.
