<p>Wikipedia is not always a good idea because it often assumes advanced knowledge.</p>

<p>No doubt, though that doesn’t apply to musicallylatin.</p>
<h2>Wikipedia is not always a good idea because it often assumes advanced knowledge.</h2>
<p>Yeah, I find it very hard to read anything technical (math, science, etc) for that reason. Your best bet is a trig textbook that assume you have knowledge through Algebra II.</p>
<p>Skip pre-calc and study trig. Pre-calc doesn’t actually teach you much of anything useful for calc (It teaches you useful stuff, just nothing useful for calc) but trig is big time important from calc all through life.</p>
<p>I have heard very good things about [this</a> book](<a href=“http://www.amazon.com/Geometry-Trigonometry-Calculus-Self-Teaching-Guides/dp/0471775584/ref=sr_1_11?ie=UTF8&s=books&qid=1246853607&sr=1-11]this”>http://www.amazon.com/Geometry-Trigonometry-Calculus-Self-Teaching-Guides/dp/0471775584/ref=sr_1_11?ie=UTF8&s=books&qid=1246853607&sr=1-11), but I haven’t tried it myself. Definitely do some trig prep before starting, though a [Dummies</a> book](<a href=“http://www.amazon.com/Trigonometry-Dummies-Math-Science/dp/0764569031/ref=sr_1_1?ie=UTF8&s=books&qid=1246853815&sr=1-1]Dummies”>http://www.amazon.com/Trigonometry-Dummies-Math-Science/dp/0764569031/ref=sr_1_1?ie=UTF8&s=books&qid=1246853815&sr=1-1) would probably cover all you need.</p>
<p>Thanks. </p>
<p>Yet again, any book recomendations?</p>
<p>I didnt take trig,
I took Precalc over the summer in 2008 WITHOUT trig nor analytic geometry, never studied, got an A.
i just passed AP Calc AB both semesters with A, i rarely studied nor did any extra efforts.
Im going to be 11th grade in the fall. i guess thats the route i took if that helps you, great!
P.S. i got a 5 on the AP exam without studying for it</p>
<p>^ I’d go with that except I’m more into the humanities. Math, not so much. I find it extremely interesting, but I’m an utter failure at it (at least by CC standards :D)</p>
<p>hey im kind of the opposite then!
i was in a Humanities class, appreciation of the arts, and i just wasnt that dedicated to it.</p>
<p>Ha, the appreciation classes don’t seem to give too much appreciation from what I’ve noticed, unless you already had that. :D</p>
<p>

<p>You honestly don’t even have to know that. I didn’t learn those trig identities well enough at all to be committed to memory when I took PreCalc. </p>
<p>The main thing you need to know is that little chart.</p>
<p>*** — sin — cos — tan
pi/6 — 1/2 — sqrt(3)/2 — etc.
pi/4 — etc.
pi/3 — etc.</p>
<p>and A.S.T.C. (All Seniors Take Calculus)</p>
<p>I’m sure you could go to your local book store and pick up a book on basic trig. There’s really not a whole lot you need to know. The main thing in Calc is derivatives.</p>
<p>^ and integrals.</p>
<p>Thanks! This is helpful.</p>
<p>are you sure your alg II class didnt integrate trig? because i learned a lot of trig (identities, unit circle, graphing sine & cosine waves, etc.) in my class second semester…</p>
<p>^ Introduction to Trigonometry is generally in a lot of Geometry and Algebra II books, however it’s at the end and is considered by many teachers to be non-essential. Plus they have so many standards to live up to that it just doesn’t get covered.</p>
<p>I disagree with BeKindRewind above. Trig identities can be very useful.</p>
<h2>I disagree with BeKindRewind above. Trig identities can be very useful. </h2>
<p>How are they used in Calculus? I’m thinking like double-angle and half-angle formulas?</p>
<p>^ We used both this year. It definitely isn’t a vital necessity to do well in the class, and you could probably just ask your teacher if they come up, but I remember wishing I had memorized them.</p>
<p>I don’t recall using them even once on the AP exam. </p>
<p>Maybe there were a couple times during the class it would have helped to know them because there were those mastery problems included at the end of each section that on a not-so-often occasion incorporated the identities, but those “mastery” problems are not tested.</p>
<p>And your teacher more than likely will just give them to you.</p>
<p>^ On the exam? Not this year. We did use them in class.</p>
