Calculus is the mathematical study of continuous change, in the same way that geometry is the study of shape, and algebra is the study of generalizations of arithmetic operations.
It has two major branches, differential calculus and integral calculus; the former concerns instantaneous rates of change, and the slopes of curves, while the latter concerns accumulation of quantities, and areas under or between curves. These two branches are related to each other by the fundamental theorem of calculus, and they make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit.Infinitesimal calculus was developed independently in the late 17th century by Isaac Newton and Gottfried Wilhelm Leibniz. Later work, including codifying the idea of limits, put these developments on a more solid conceptual footing. Today, calculus has widespread uses in science, engineering, and social science.
Mathematics tends to be more progressive than any other field. But I've heard some people say that some math classes that they took were more difficult than the most advanced math classes that they took. For instance, I've heard people say that Calculus II is more difficult than Calculus III...
If I were to read up to and including Chapter 3, would I be prepared enough to read Spivak's Calculus or at least some single variable calculus text based on proofs?

I work full-time, so evening or online classes are all I can do. I need to take calculus from the community college I've been attending, but it is not offered in the evening. In fact, none of the local colleges or universities offer it in the evening, so I must do it online. So I go to register...

Find a continuous funciton ##f## such that
$$
f(x) = 1+ \dfrac{1}{x} \int_{1}^{x} f(t)dt

I think I solved it but I would like to see if it's right.
Well, first of all, by the fundamental theorem of calculus I know that

Hello,
I am a Computer Science major still knocking out some of my gen eds. Unfortunately, today I found out that a made a 79 on one of my final Calculus I tests. This has brought my letter grade down to a mid-high B. I was planning on taking Calculus II over the summer, however, now I am...
Hey guys,
I have a couple more questions about this problem set I've been working on. I'm doubting some of my answers and I'd appreciate some help.

For the first one, I evaluated by replacing x for 2+h for f(x). Then I substituted into the givern expression and simplified to get...
Hey everyone, I was hoping I could get some input on this. I'm taking an honors section of Calculus I this semester, and part of the course involves a cumulative honors project. It has to be a minimum 8 page paper, at least a third of which has to be actual calculations, about a topic that...
lim of (3^y-5^y)/(2^y-7^y) as y->0
Evaluate the above limit.
Okay, so, I was flabbergasted at how challenging this problem is. I realized it was an indeterminate form [0/0]. I was trying to find a way to cancel y out of the numerator and denominator, in vain. I tried finding a pattern to...
Hi there, I've got a bonus question from my calc class that I've been working on. First off I AM NOT LOOKING FOR AN ANSWER. What I really need is for someone to break my algorithm and point me in the right direction so I can keep working on it and hopefully--if it's not too far over my head--I...
I'll be taking these two classes together this fall (along with an intermediate college writing class and a one-hour-per-week mathematics computing lab).

I recently took a calculus readiness given by a special program for high school students in my area called the math and physics institute (MPI) to see which math and physics classes I would be taking my senior year. I scored well enough to be placed in the most difficult section of the program...
I'm scheduled to take Calculus II this Fall semester, but it will have been over a year since I'd taken Calculus I. I am aware that I need to review, but what are some are the major concepts I should review to adequately prepare for the infamous Calc II?

Hi again, my calculus exam is on monday so trying hard to understand the things I'm struggling with. I think I'm almost there with part a - well I can solve it through drawing a graph or using a graphing program - but I'd rather solve it without graphs if possible. Part b however is causing me a...

1.) lim x --> 1(left) (x^2 + |x| -2)/(|1-x|)
Since the limit is from the left, i made all absolute values pnegative, therefore numerator = x^2 - x - 2, and similarly denom. = (x-1). Then, by inspection, the limit would equal to + infinite.
2.) Find numbers a and c such that lim x --> 0...
