I'm thinking of taking calc 3 sooner or later and while I know my derivative and anti-derivative, I find myself forgetting some of the more practical and usefull formulas. I still have my book but was looking for a kind of refresher because I'm sure I'll remember once I start. Not to mention my failure in Prob and Stat was partially because of my lost memories of calc.

look around here to start: http://www.jimloy.com/math/math.htm
hope it helps. :)

Ah, Calculus (note, capital C!!), my good friend! IT seems that's ALL we do in Elec Eng -

Integrating surfaces, lines, areas, volumes, double, triple integrals, infinate integrals, doubly infinate intgrals, Green's theorm, moore's theorm, divergence theorm, heaviside step integrals, and finally integrating the slope of ice creams, finding areas with integration, finding volumes with integration, finding work done with integration, complex line integrals, complex area integrals (possibly), complex volume integrals (possibly), Stoke's theorm. I'm sure there were LOTS more, but I can't remember them.

Sorry, no help on the online side. Haven't looked at it, but try wikipedia.

Signals and Systems was fun!!!

But seriously why dont you just go over your calc 1/2 assignments and try a few problems. I find the only way I ever understand is doing problems.

A good book (if you have cash to burn) is Advanced Engineering Mathematics by Kreyzig. I would recomend that one.

>> Advanced Engineering Mathematics by Kreyzig

My good friend!!! It's very good, but sometimes kinda vague. It covered lots of our subjects last year, and it was recommended to us.

I did my my best problem solving in Calc, and programming classes. I fear I had a much harder time in physics and statistics.

It's the absolute best reference for solving diff. equ. It was so much clearer than my profs stupid lecture notes! maybe not so much for algebra part of it.

p.s. I like your title under your name

dont get me started with physics/electromag...pfff actualy using what you learn in calc 3...what kind of class is that...

Kreyzig saved my @$$ this year, but it might be overkill for what you need,
there's a lot in it. I used it in studying Laplace and Fourier Transforms, prob and
stats, and for reference for the basics of multivariable calculus. Excellent book,
any recent edition (9th is latest, but I used 8th) should be up to scratch, very
diverse as you can see, so that's why it might be overkill. All I know is that I'm
not selling mine!

indigo0086, after a long time searching, I found a good Calculus reference! (http://uncyclopedia.org/wiki/Calculus)

Yeah! I wasn't saying I didn't like it!! I'm in RichieT's class, and I used it for all the things he used it for, and it saved by butt during the exams, I can tell you. The good olde' superhetrodyne decoder thing :) I remember learning about it in Telecoms, but I've forgotten about it, other than diodes and other things being there ... it reminded me of a bridge rectifier, but that's not the point.


Edit - And some Multi Var (http://uncyclopedia.org/wiki/Multivariable_Calculus) stuff

Pre-calculus is not so much a branch of calculus as it is a ruse to make new recruits believe that calculus is easy and safe. It consists of a rudimentary survey of the two principal principles of calculus:



Not EVERYTHING there is false.

I don't even know why pre-calculus contains "calculus" in it's name. It should just be called "harder basic math". I don't even remember doing differentiation or integrals in pre-cal anyway, not even introductions.
