I think it is needed when you use applications like matlab and matcad where you have to use equations to do some calculations?

Perhaps, but there are CS domains that use calculus; just because you program and don't use calc doesn't mean computer scientists don't use it :p

No, but it means not all computer scientists use it.

So what did I say that refuted that point? Nothing.

Are you fabricating an argument here or something? You seem intent on discrediting my statement which was merely pointing out that calculus is not necessarily used in "the real world" even by some computer scientists.

I hate the "when will I use this in the real world" argument. You are in college not a trade school. College is a place to learn new things and as a side effect you can get a job you couldn't have gotten before. Trade school is the place for the "real world" crowd they won't try to expand your understanding of the world at all they will only teach you what you will need for whatever job you are trying to learn.

Most things around you use calculus, atleast the basic concepts of integration and differentiation. Your cellphones have circuits that mimic an integrator & differentiator that are used to transmit/recieve data wirelessly. Electronics use those concepts for image processing, sound processing, A/D conversion, noise cancelling/filtering, etc...

It's everywhere!

I never said all computer scientists used calculus. Rather, you are the one who chimed in and said that you don't, which I never disagreed with.

To my knowledge, calculus is not a required course to graduate from high school, so why are you taking it if you just want to do the bare minimum?

Suggested reading for OP JEDI An easy 10 pages to breeze through

Calculus is the mathematics of motion, change, and optimization.

For tons of examples of "real world" uses, just read the problems in a textbook.

*What production level maximizes profit?
*Given some some function describing customer response, what % of target market is expected to buy a video game offering if advertisements are run one time on MTV?
*Your company makes 3 products, each which must be processed through 2 departments. Given hours required per unit of product in each dept., and dept. capacities, what combuination of products will exhaust the weekly capacity of the 2 depts.?
* Interior & exterior walls of a rectangular office cost $150 per running foot. The office is to be divided into 10 rooms by 4 interior walls in the X direction and 1 wall in the Y direction. What should the office building dimensions be if wall cost is to be minimized.

etc. etc. All calculus.

Are there any more math courses that are based on calculus? Just curious because I'm a math minor with a lot more to go....

Boy there sure are a lot of young academic elitests in this thread.

Just like dullard said, you use calculus on a daily basis for the most basic of life's functions. Though natural math, physics and calculus are something a human can do without needing the ability to put it on paper. The fact that you can translate it to paper explanation only means you have mastered the ability to utilize a human system construct to explain something. The vast majority of the world will never need to utililze thoes systems to explain what they are doing. Sure there will always be the need to have people who use thoes systems on a daily basis to create the things we use to live. On the same note, we will also need people who shovel sh!t out of ditches so you can get fresh water from your tap everyday.

Quantifying the important of one over another is nothing more than a practice in elitest futility. Why so many of you turn your noses up to people who don't give a rip about explaning calculus, I'll never know. Come back down to earth, it's warm here. Your mother misses you too.

That will depend on the school but most have differential equations. I would ask a math professor or the head of the math department if you want a full list.

I'm pretty sure I have to take differential equations. I know I have to take discrete math and applied matrix theory.

The school I went to had two levels of discrete math one which required taking calc 1 first and one that didn't. The one I took tiptoed around the calculus which was annoying for someone who had taken it. So while I don't know for sure that it will use calc I would say probably will for some parts.

As far as applied matrix theory goes I wouldn't know, but if it requires calc 1 or greater to take it be prepared for some calculus to be used in it.

In my experience computer programming isn't a particularly intellectually demanding field. It seemed pretty rote but I guess that depends on what you're doing

I found it kind of amusing that after taking several years of higher math, once I started sinking my teeth into computational biomechanics about 99.9% of all the math I do now is +,-,*, and /

Computer programming is a trade skill and isn't equivalent to a computer science education.

Not sure what you are saying here, but if you are claiming that the topics covered in the average comp sci education do not apply to programming positions in the market, it depends quite a bit on the position. There are tons of positions where it will be advantageous to have a comp sci education.

Calculus is used very heavily in Statistics, expecially Baysian Analysis and Time Series.

yea, that's one reason I enjoyed my business calc - the book problems were all real world business problems and you could easily see how they related to the business world.

we're using calc right now in msis - productions operations management, and the follow up course business dynamics

Look, the majority of people don't "need" a college education at all. Except for technical fields (which COULD use the old master/apprentice system, college is just an easier way), you learn everything you need for basic life in high school and individual experiences.
