So I was thinking about taking this class, just for the fun of it. I've already done the first two and they were pretty interesting. So I was thinking about taking Cal 3 to complete the entire series. For those of you that have taken it, how was it? Did you learn anything new (except for series and triple integrals)? A friend of mine told me that Cal 1 is easy, 2 is hard, and 3 is easy because it's an advanced review of 1+2. Is this true?
😀

I am taking it in the fall too. i would like some good responses.
 
i took it last semester. it's definitely easier than calc 2 since you already know the foundations of calculus...calc 3 is just like calc 1 except, as posted above, it is multidimensional.
 
I just hope the Vector stuff doesn't get too hard, lol.

What is calc III? I've never heard of that, just calc I (single variable) and II (multivariable). I am assuming it's not the same thing as diffy q?
 
Differential Equations is a separate class after Calc III

My school has it like this:
Cal I: Differential Cal.
Cal II: Integral
Cal III: Multivariable
 
cal III is multivariate calculus. Although the concepts taught are complex mathematically, the actual work required is minimal because it begins to require the kind of labor that we all rely on computers to endure.

Most all test questions were like: Set up the integral (up to you to decide what kind) necessary to determine the surface area of object X given by some formulaic boundaries.

So not all that much computing to be done, where most of the mistakes occur. In that sense, it will be unlike your previous math classes because your success will most likely be directly dependent on your ability to wrap your head around what is going on rather than that in addition to your ability to compute the numerical answer.

I liked it.

That's how my school did it.

Calc III was actually required for my major (a biology-related major) - I thought it was pretty fun.
 
Calc 3 is multivariable calc in multiple dimensions. It's also mostly vector-based. Personally, I thought it was by far the hardest of the 3. It's fairly useless if you don't plan on doing any further math or any intermediate/advanced physics. Probably the only thing you'll learn that might be kind of useful if you really try to apply it is the gradient function.

Diff eq, on the other hand, is extremely cool and very applicable. If you're interested in taking another math course, and your school lets you take that without Calc 3, I'd suggest doing so. Pharmacokinetics will make a hell of a lot more sense with a little diff eq background.

Interesting. Guess we do a more compressed version. Anyway, I liked multi, found it very helpful in other classes (all of our sciences are calc based).
 
Thanks for the advice everyone. 👍

The thing I found it most useful for was translating what the hell was really going on in E&M. I was like, here I am modeling a surface, oh, now I get what the E field really means given that it's surrounded by the surface...etc. Ad nauseum. 😛
 
I, like most people I know who took it, found Calc III to be really easy and fun. However, I do know a few people who didn't like it much. Those were people who have a hard time envisioning and working with multi-dimensional shapes in their head.

So, if you find this hard, or just don't like it, Calc III is not the class to take for fun.
 
Sounds like lots of fun :meanie:
 
My school is also Calc I/II/III. I've only taken the first two, but would you recommend III as well if I'm going to take the calc-based physics sequence? (I already took one term of algebra based but may start over with calc and finish the sequence).

E&M is my mortal enemy. I don't imagine many premeds take enough physics for Calc 3 to actually make a difference, but if your life goes horribly wrong and you do find yourself in an intermediate E&M class, Calc 3 will be your best friend, conceptually.
 
In my university, Calculus goes like this:

Elementary Calculus I and II
Intermediate Calculus I and II
Advanced Calculus I and II

Would my Intermediated Calc I be the same as Calc III for you guys?

Because im taking it as well 🙁

Yes, just take it. At my school, they way it works is that Calculus I,II,III are Pre/Co-requisites, so without taking them you can't enroll in the Calculus based physics series.
 
calc three is the best of the 3, much more interesting than regular differential equations and easier concepts than integrals

Yeah. At my school everyone is required to take both single & multi calc, and calc based physics I & II. I was taking multi calc at the same time as E&M, and after the second half of the semester, when I had some multi under my belt, E&M started coming together. Until then I was completely lost. In a lot of ways I don't think you can really get E&M without multi - the algebra based stuff really doesn't convey what's going on.
 
When you say E&M, are you referring to electricity and magnetism? Jw lol
 
Take it. I loved Calc III. It's like I and II, just adding in extra dimensions. Once you understand how to do this, Calc becomes even more applicable. It's awesome.
 
As an indian brother, you are innately tied with all things mathematical - you are a problem solver and you will be doing yourself (and your GPA) a favor by destroying your Calculus 3 class.

Suggested reading: Stoke's Theorem and Green's Theorem

God DAyuum...Straight up mind-reader :laugh: Couldn't have said it any better, lol.
 
In my school theres Calc I and II (single variable), Calc III (multivariable), Calc IV (Diff EQ).

Calc III was pretty easy. Much easier than calc II IMO. You didn't need to know all the ****ing complicated rules for integrals, just the basics applied to three variables, which isn't as bad as it sounds.

Calc IV was fun as well. I liked differential equations.
 
I think that like any math/science class Calc 3 can be as easy or as difficult as the teacher makes it. The general consensus for people at my school (UF) is that calc 3 is probably the easiest of the three, but there are also teachers that make it a real bitch. I personally found it to be a joke, but I do know people who struggled in it. If you do take it though, I would highly recommend taking an elementary differential equations class afterwards because that was probably the math class I enjoyed the most and found the most useful.
 
Multivar was the easiest class I've ever taken. Got a 99 on the final. 😀

You basically do the first half of calculus, just in three dimensions. It's so easy.
 
The triple integration was no problem. It's all the vector crap that got me screwed up. I'm not sure why, but vector calc has never made all that much sense to me.
 
I took it and it was not particularly hard, I thought. But it was one of the reasons I switched from my math-heavy major to a bio-related one. I guess it just didn't strike that "oooh, this is awesome" note w/ me
 
Sadly, I get to take calc III twice. I'm doing my frist 2 years at a cc, then transfering to a university. Because of the way classes transfer, calc III counts as a generic math class when I transfer, and it is required for my degree, so I have to take it a second time at the university.
 
Calc I: Derivatives
Calc II: Integrals
Calc III: Multivariable
Calc IV: Vector Calc

then for kicks:
Linear Algebra
Differential Equations
Abstract Mathematics
 
^^^ Are you a Math major or minor?
 
I remember thinking about EE...Until I saw the Circuit Analysis Book. lol.
 
Calc I: Derivatives
Calc II: Integrals
Calc III: Multivariable
Calc IV: Vector Calc

Different classes for multivariable and vector calc? How do you have an ENTIRE course on vector calculus?

I think what they did is take the Vector stuff out and introduce it in a separate class. It could be a quarter system, or perhaps that's just how the school breaks up the sequence...?
 
Calc III was a fun class. I just love osculating planes 👍

DE seemed alot more applicable, however.

1- To complete the series, you will need Differential equations too!
2- calc 3 is easier than cal 1 and 2 (I thought calc 2 was the hardest)
3- I can't remember a thing that I learned in calc 3... funny thing is that I'm engineering grad! god sometimes i feel like returning my diploma!

you are correct sir.. or madame? My school was quarter based so calc IV was vector analysis. you know, line and surface integrals, green's theorem, stoke's theorem, divergence theorem etc...
