<p>I took Alg II/Trig last year and I'm taking AP Calculus AB this coming school year. Is there anything in precalc that might be on the Math II test that I won't learn in Calc?</p>
<p>Vectors…Matrices…Probability? I think that’s about it.</p>
<p>I didn’t really study for the Math II test, so I may be missing some things.</p>
<p>Thanks! </p>
<p>I don’t know anything about vectors. ._. We learned about matrices, but I don’t remember much about it. I just remember it was easy but it took forever. Does that sound about right? And how difficult is the probability? Is it just SAT I level probability or is it more advanced?</p>
<p>Ah so many questions sorry. @_@</p>
<p>Umm, vector problems usually involve adding them, subtracting them, and finding the angle created by 2 vectors. I believe matrix problems deal with multiplication and determinants (both of which can be done with a calculator). The probability is rather simple. Also, be able to find the standard deviation of a list (either by hand or calculator (calculator is the preferred method, of course)).</p>
<p>Anything else? I’d be happy to answer any more questions.</p>
<p>Thanks again! : D It seems like I need to teach myself about vectors, but otherwise I just need to review some things from alg II/trig and learn other things in calc. So precalculus isn’t really necessary in my case, right?</p>
<p>Well there are some basic limit questions which are the first thing you will do in calc.
Also, make sure you review your postulates and theorems from geometry as well as synthetic/long division.</p>
<p>Muchos gracias senor(ita?). Do you know if Barron’s goes over that stuff? Or am I going to have to dig up my old geometry notes? (Knowing me I probably threw them away. -_-)</p>
<p>^^You don’t need to memorize the theorem verbatim, do you?</p>
<p>Can’t go wrong with Barron’s.</p>
<p>Here is what I did:</p>
<p>Freshman Year: Algebra II Honors + Geometry Honors
Sophomore Year: AB Calculus AP
Junior Year: (to be determined, most likely MV Calculus)</p>
<p>So basically I completely skipped PreCalc. I learned trig in like 30 minutes altogether and winged the Math IIC and got an 800. PreCalc is really a waste of time. You review Alg II for a year…</p>
<p>^By learned trig, do u mean you memorized all the formulas and sin, cos, tan values for all of the common degree/radian measures? Because that is pretty impressive</p>
<p>^no the only formula I memorized from trig is this:</p>
<p>s^2 + c^2 = 1</p>
<p>From there, if you can derive all the other equations…</p>
<p>Also, if you want you can enter in all the trig formulas into your calculator. I didn’t even memorize the unit circle measurements. </p>
<p>One formula worth memorizing is this easy one:</p>
<p>Sin 2A = 2Cos(A)Sin(A)</p>
<p>GreedIsGood you’re amazing. @_@</p>
<p>Does that first formula mean sin x^2 + cos x^2 = 1?</p>
<p>
</p>
<p>Yes.</p>
<p>I also agree that Algebra II is essentially the same as Precalculus. I skipped Algebra II and took Honors Precalculus as a freshman and BC Calculus as a sophomore. 800 on Math II and 5’s on BC and AB subscore. That being said, I’m a strong math student, so many students need the 2nd year of review (i.e. Precalculus after Algebra II) in order to succeed in Calculus.</p>
