AP Calculus AB

<p>Okay, so I had my first test on limits and I did pretty bad. We are starting the topic of continous functions now and will probably move on to derivatives. The book we use in school is almost 15 years or so old and HORRIBLE, i've been looking online but are there any really good self-prep calculus sites you guys know? Please help!</p>

<p>Try calculus.org</a> - THE CALCULUS PAGE .
What do you need to know about limits?</p>

<p>I can just tell that your book is bad - why wouldn't limits and continuous functions be included in the same chapter? After all, you can't mathematically define a continuous function in calculus without limits.</p>

<p>Honestly, I would think that your online resources are fairly limited. Try to get another textbook secondhand or maybe a prep book.</p>

<p>thanks guys, and that was my second option, to try and get another book. I dont need to know anything specific regarding limits but just trip up on few problems.</p>

<p>yeah my current textbook is 20 years old. So I got a newer one that explains things better. Just had my first test too..I think it helped a lot.</p>

<p>Don't worry, I feel your pain.
Not only is our Stat teacher bad, our book is 17 years old :]</p>

<p>Also, limits should be easily learned.</p>

<p>In a typical function, plug whatever X is reaching.
In a rational function, factor first.</p>

<p>If the limit reaches a # when X approaches infinity, there is a horizontal asymptote
If the limit reaches infinity when X approaches a #, there is a vertical asymptote.</p>

<p>When you are drawing the function from limits, just draw the ends. :]</p>

<p>That's a crash course on limits. lol</p>
