# Mathematics

In one of my classes, it was necessary to review Laplace transformations. I realized that, after many months of not using it, I had become extremely rusty in integration by parts. Once I saw the basic idea, it slowly came back to me. Therefore, and I know the core audience isn't exactly appropriate, I would like to do a series of math related instructables AND I would like to have one or two collaborators. There's a few reasons I'm doing this.... 1. I feel the internets lack a resource with basic instructions of advanced mathematics (there's a few good resources, but it's mighty hard to find a "how do I do this" sort of thing). 2. Teaching is a great way to refresh the memory 3. The potential of comment feedback could be a good indication on what else should be covered. 4. Perhaps earlier basic introduction is useful to someone? Or not.... 5. The focus, in addition to how, is why such things are done. You won't find that on wikipedia :p Some topics to include (not necessarily individual projects) - and the projects would be something like How to solve _____. Basic definitions - notation Differentiation Integration Fundamental theorem of calculus Chain Rule Separation of Variables Integration by Parts ODE's Laplace transform Fourier Transform Anyone interested in collaborating - even on one subject? Then, anyone interested in looking at these? Not necessarily to learn how, but to see why it's done? For the why/application - I mean given a real world scenario... I promise, the application portions won't be boring (at least not for the nerdy type) ;)

I could do a statistics instructable. Between my tests and measurements and biostatistics classes, I am well versed in the subject material. I actually hate math, but for some reason, I think statistics is a little fun. Finite math, however, is the DEVIL!

Have you ever dealt with non_real numbers :-) There's some fun....

I'd love an FFT for dummies, without all the Greek would be super! 25 year old question: Where do all the coefficients go on large Butterfly diagrams?

I'm very interested to learn from and to understand what it is useful for. Though, unless you want to get some feed back (and lots of questions) from a ex math class heavy sleeper, who's now full of regrets, and who may need a lot of basic introductions and preliminary explanations/lessons, I'm afraid I'll be useless .......

This is a neat idea, but the instructables format can't really display the mathematics properly. You could make a bunch of pictures of the formulas and post those, but it'd be much simpler to write it in LaTeX and post a .PDF.

Hrmm... a PDF is a pretty good idea :p I planned on getting images etc. through MathCAD.

Think I can help out. A bit rustic though, haven't played with differentiation, integration, etc in years..

. I'm not much on advanced math (never studied Calculus or anything like that - integration is magic to me), but I have a _little_ knowledge of Statistics (helped my ex study for her MS and PhD Psych) and had Chem/Phys/Geom/Trig in high school (35 yearrs ago, so don't expect me to remember much). Have the CRC Handbook of Chem & Physics (great ref for all sorts of stuff, not just chem/phy) and misc college math texts - some of which I actually understand heehee. . OK. Now that you have my mini-CV, I'll volunteer to proof-read and/or critique. With a decent reference (I believe I have a Wiki markup ref bookmarked), I should be able to help with formatting, too. Also available for misc grunt work, eg, fact-checking. PM me if I can help.

Aye, after being away from it for over 30 years, I could use a bit of a brush up that most books just lack the substance with.

I'll help! I haven't used this stuff in years, but it will be good review :P It should probably done in order. (You might have thought of that, but your list is out of order...)

Awesome Idea, but being in Honors Algebra II, I doubt I would be of any help. But as I move up in math, I would definitely use the Instructable as a tool. Especially because the main math teacher at our school is.......different.

Especially because the main math teacher at our school is.......different.And by "different" you mean completely normal.... It's the "normal" ones that are different :p

Good idea! Unfortunately, I'm not yet in a high enough math class to help, or I would.
