I need help with pre-calc

Recommended Posts

Two weeks ago I quit my job and went back to school full time. I haven't taken a math class since 98, but I tested into pre-calculus trig and came close to testing directly into calc itself.

Problem is: I've forgotten some of the fundamentals (and some I was never that good at to begin with). So: I need help with certain aspects of pre-calc (namely that I just don't seem to understand the concept of factoring or solving certain equations).

I've looked around at several sites on the 'net, but have not found any really good ones yet. My teacher is far too busy and unwilling to help me re-learn these things, and the tutors at school are swamped right now, so I can't get any help there. Also, it seems that of the 15 or so students in my particular class, I'm probably in the top 3-5 in terms of understanding the material, so I'm not learning much from my classmates either.

Short version: does anyone here know of a good site/book that I can read to learn this, or might even be willing to personally help me?

Thanks,

Mike

There are a few good books out there... I came across one called "Pre-Calc in a Nutshell" a few years back. It did a pretty good job of covering the basics. Try you local Barnes and Nolbe for books like that.

Some school text books are pretty helpful once you get going, but others are just not worth a cent they charge- my "calc for eng['s]" for instance uses stupidly complicated phrases to describe simple operations.

Have fun with integrals when you get there... they're a blast...

Best of Luck

I've received several PMs from people offering to help, and I really appreciate it. I'm also going by B&N today to look for some books that might help.

In response to WingNut- I prefer math. Firstly, I'm pretty set on being a software engineer (computer programmer), which pretty much requires a computer science degree. Besides, the arts are hard and way too ambiguous. At least with math there is always an answer. I may be too stupid to find it, but it's there, somewhere....

Thanks,

Mike

okay so i'm gona admit i don't know what the word ambiguous means.. but i didn't mean just like painting or music.... was talking braod like philosophy to language to even actual arts like music....

i could always do math in school just fine, understood it but just don't want to put the work in for it.. good luck! have a friend that got his masters in computer science last year he's working for a gaming compnay in san fransico, his first game he has worked on will be out the middle of this year...

I've done game development as a hobby since I was writing code on an old Commodore 64. I've pretty much decided that pursuing that as a career is both unrealistic and stupid. The game industry is way too unpredictable to make a good living, and the working conditions are not all that great. I've got several friends working in the industry, and they have all been laid off at least once or twice due to cancelled projects or feature cuts.

The strange thing is, that with all the code I've written for games, I can do some pretty advanced math instinctively (like 3 dimensional vector math, rotators, quaternions, etc), and yet some of the simpler stuff just eludes me.

The main points of pre-calc are Functions, Limits(gotta understand limits) basic algabraic manipulations, and trignometric laws and identies. Oh yea, and conic sections.

I used to have a really excellent pre-calc text, less than an inch thick, with an orange and blue design on the cover, with cool three color graphs. Try used a book store, or the school book store.

I'm fairly sure this is a newer edition of that book:

I need to get another copy of this book too. Somebody burned mine, along with every thing else I had in a tent some years back.

I don't even know what MathCAD or the CRC handbook are. Also, I can't really afford to forget any of what I learn in this class because I have to take at least 3 other courses that are built on what I'll learn here.

I've found out that there is companion book for my textbook that has all the odd number problems worked out and explained, and I'll be buying that this week. I'm pretty sure that seeing them worked out will kick start the nether regions of my brain that have long since forgotten things that used to be second nature. If not, I'm probably screwed :P...

You will ;)

That book is really good. Its what they gave me when I tested a little deficient to start calc. And, its what I bought again used, when I wanted to brush up to finish my calc sequence on my own. :)

Im in the same boat as you, fortunately, I work with an Engineer that just received his masters in Computer science and he offered to be my tutor... Boy, bet he will be sorry later.

On the point you were asking about, I found a book with problems and answers and questions, etc at the college bookstore. It might help.


Good luck

take the time to appreciate the people around you.
