## I know enough calculus to think of the question but not the answer

You want to walk 10 blocks north and 10 blocks east. It would be shorter to walk along the hypotenuse, but the same distance to walk 1 block north, then 1 block east, then 1 block north, etc. it seems that if the blocks were infinitesimally short, it would approximate the hypotenuse, but alas, walking 10 blocks in one direction and then 10 blocks in the perpendicular direction is the same as dividing it up. What gives?

Wanting to code. Can't read calculus. Kinda stuck. Help? [more inside]

## Math Filter: What is Calculus?

My son would like to know: Is there more to calculus than functions, examples of functions, various formats for presenting functions, and so on? That is, does calculus have unique to it other tools that are not just variations on functions? [more inside]

## [MathFilter] Taking for-credit math classes online

For professional and academic reasons, I need to take a number of college-level math classes (mainly Calculus and Linear Algebra) in a relatively short period of time (4-6 months). They need to be online, for-credit, and I need to be able to do them at my own pace, meaning faster than a normal 1-course-per-semester flow. I've already found https://netmath.illinois.edu/, but the classes are terribly expensive, so I'd like to learn of other alternatives that don't cost as much.

## Calling all chem- physics- and math-philes!

For the grad-level education I want, I need an understanding of chemistry, physics, and calculus at a minimum. I have a BA in a tangentially related field (or will in a couple months). What are the best resources for learning these subjects without spending even more time/money on tuition? [more inside]

## Group Work in Math "Lab" + Introvert = I'm Freaking Out

I'm taking Calculus this term and have just found out the second half of each class will be group work and I'm freaking out. I'm an introvert and the thought of working in a group - especially where I don't feel confident about the subject matter - is making me anxious before the class even starts! Can anyone tell me what to expect and/or offer suggestions on how to make it less awful? [more inside]

## Basic Math for Math Majors

Hello! I'm a first semester grad student in applied math. I am a non-traditional student in a variety of ways (liberal arts undergrad, working full-time), and while I'm finding that I

*intellectually*understand the concepts I'm learning, execution is being made difficult by my lack of fluency with algebraic manipulation and calculus. [more inside]## Not my high school TI-82.

I'm taking Calc I this fall. I can borrow a graphing calculator for actual exams, but don't want to actually purchase one for day-to-day--or haul it around with me. I have an iPhone and a Nexus 7. Is there a graphing calculator app in one or the other app store that is clearly superior? I'm willing to pay, but under $10, ideally.

## Textbook Cross-reference for different editions

Is there some place I can find cross-reference guides to match up material and problem sets between different editions of the same textbook (specifically math textbooks) ? [more inside]

## Online Math Tutor

I'm a college student who is having some issues really understanding Calculus II, which is a problem as A) I am a Comp Sci major, and B) I need to take Calc III as well, and an advanced math elective as well. I've not heard good things about the school provided tutors, (IE, one is not too skilled at math, and the other is really smug and poor pedagogically) and while I could get a private tutor to help me, I was wondering if there are any good resources for online math tutors, like there are for online language tutoring over Skype. Does a directory of such tutors exist, has anyone had a good experience doing this (maybe even with names?), and how much can I expect to pay? [more inside]

## My Trig Teachers Name Was Mr. Angle But That Didn't Make Him A Good Teacher.

## Seniroitis

I'm seriously fucking up my senior year of High school. Senioritis is just the worst. Is [my university] going to drop my scholarships or acceptance? I need to know if I have to take drastic measures now to prevent screwing up my whole life. [more inside]

## Some good books to re-learn math?

I'm teaching myself to code (Python, mainly), and it's going well, except I keep on running into one big problem: I haven't done any math since high school (6 years ago). I used to be top of my class, and now I can't do simple word problems anymore. This gets tough because they inevitably pop up in the books I'm using, and then I stop dead in my tracks. Could anyone recommend a couple of books or web resources to help me get back up to speed? I never took Calculus, so a good Calculus book would help, too. [more inside]

## I still KNOW the quadratic equation, just not what it means

I have forgotten basically all of math, and I want to learn it again from the ground up. [more inside]

## Next step: solve in three dimensions

Calculusfilter. A man is led to the center of a valuable field which he does not own. He coats his feet in blue paint so that his path can be traced. At dawn he begins walking. At a randomly selected time he will be told to stop walking, whereupon he will walk in a perfectly straight line back to the starting point. Then he will be given all the land that has been circumscribed by his blue path. [more inside]

## What is/are the best option for studying calculus online for university credit?

I currently work and live in Beijing, so don't have the option of studying calculus locally. (At least, I can't study it in English.) I am interested in starting to study calculus for credit (and a grade) in anticipation of my return to the States in two years and applying to graduate school. Can anyone give recommendations or reviews of online calculus classes? [more inside]

## understand calculus

I've finished first year calculus (diff./int.), but I'm not sure I understand fully what I've learned. Can anyone point me to something, not too technical, that might help.

## Help me remember math!

I'm taking a calc-based physics class as well as a calculus class. The last time I took a math class was 5 years ago and I would love some refresher resources - or even better, an intensive algebra-trig-precalc course. Are there any online or in the DC area? [more inside]

## Principle domain of a polar equation?

I need help understanding the "principle domain" (a term only my professor seems to use) of a polar function. That is, how do I find the smallest value delta such that [0,delta] plots all of the unique points on the curve; any values greater than delta re-trace points. I suspect that if MeFi could identify the more common name for this, uh, procedure, I'd be set.

## Help me publish a calculus textbook.

## the maths, get them in my head

I need to learn Calculus II over the summer. I won't be able to take summer courses. I need to be ready to take differential equations in the fall. Hope me! [more inside]

## I am sick of having to say "I'm not good at math."

I have always had difficulty with mathematics. Now I'm in my mid-thirties and have gone back to school to study engineering. Things are not going appreciably better than they did the first time I went to university. What can I do to fill the gaps I have and become a skilled problem-solver? I want to go from being a C to being an A student. [more inside]

## Fourier series confusion and pre/post-integration substitution dilemmas.

Asking for a friend: With the use of Fourier series, I'm trying to solve an ODE of the form L*y'' + R*y' + y/C = r(x), where r(x) = 1 - x^2 for |x| <= 1, i.e. has a period of 2. To do so I need to represent 1 - x^2 as a Fourier series. In doing so I have to integrate e^(-n * i * pi * x), but I've reached a stumbling block. [more inside]

## Need an example of a divergent alternating series

I'm looking for an example of an alternating series: the terms of which are (-1)^n b_n, where b_n -> 0 as n -> infinity, but the sequence {b_n} is

*not*decreasing, and the sum from n=1 to infinity*diverges*. [more inside]## Math basics need be strengthening

In need of some daily source of random math problems (upto basic calculus) that will reinforce or (if necessary) re-establish some real fundamental concepts in the algebra portions of calculus, unless something else might work. [more inside]
