Pre-Calc resources

[skyclaw441]

I'm going into Pre-Calculus next year, and my math scores have not been great this last year. I want to kind of get a head start on Pre-Calc and really understand what I'm going to look at (there's no point in trying to save my Algebra II grade, I have five days of school left). Can anyone point me in the direction of some good, free Pre-Calc resources?

Hmm, there really isn't a lot of Pre-Calc out there... Basic math up to grade 11?

Why don't you just find a calculus book and learn some of it on your own? The first part of it really isn't a big deal..

How far are you looking for? Into integration? Derivatives? Trig?

Just to get me through first semester, so I can explore it more on my own later on as well.

first semester is mostly detailed review of concepts you learned in algebra two. After which is trigonometry.

I can help you with trig, I think I have pretty good notes that lay out the foundations pretty nicely, starting with the unit circle and onto all 36 identities.

Looking through my first semester notes now here is some of the general overview.

1. Knowing the 6 types of functions, (linear, square root, absolute value, quadraic, cubed)
2. rational functions, exponential, logarithmic.
3. Sums, geometric sequences, infinite sequences, artihmatic sequences,
4. interval notations, ranges, domains, inequalities
5. determening zeros of polynomial functions, long divison, synthetic division
6. asymptotes, oblique asymptotes
7. having to figure out x,y, and z from 3 given functions using all 3 variables.
8. then it gets into logarithms
9. imaginary and real numbers
10. pascals triangle
11. and you will brush over limits.


2nd semester is mostly trigonometry.
1.unit circle
2. radians
3. converting between them and degrees
4. sine cosines tangent
5. secants, cosecants and cotangents
6. graphing all 6
7. proving equality
8. and you will end the semester off in vectors

Ahh! Fuck! I hate Algebra II. But, I guess I could just pay extra attention to what's on the final. I'm good at the basic trig I did in Geometry, so trig doesn't sound terrible.

You have a graphing calculator, right?

I believe a pre-calculator was called an abacus

[skyclaw441]

Well, I borrowed a Pre-Calc textbook from my teacher for the summer, and I'm studying out of that right now. So far, I've been graphing manually, but I need me a graphic calculator. I'm looking at TI-83s, those are $100 new or $50 used.

Nooooooooooooooooooooooooooooooooooooo!

There's tons of those online, don't waist your money.

^-- good for calc 1,2,3.

I'll teach you pre calc. Online. On skype. :rant:

If you want something to use in class, I'd recommend at least a TI-86, which should take you through basic calculus. If you're not looking for something to use in class (as others have said), just use the Internet.
