<p>Pre-Cal is considered Calc A?</p>
<p>ya u go to AP calc bc after</p>
<p>At my school you take pre-cal then go to cal ab or cal bc…I’ve never heard of pre-cal being credited for cal ab.</p>
<p>Pre-calculus is half year trignometry and half year Caculus 1. People that take AP Calculus AB must have did bad in Precalculus.</p>
<p>I’m in honors so we do Calc A during the school year. =D</p>
<p>
</p>
<p>My pre-cal wasn’t half a year calculus 1. I’m in cal ab (by choice) and I had about a 96 average in pre-cal.</p>
<p>What makes calculus so hard? I am curious… (note, I have never taken Calculus… yet).</p>
<p>Calculus is not truly hard in concepts, you just have to be very fluent in algebra and trig. Also, you have to like math which most people don’t do

<p>IMO the best way to learn vectors is through a physics book. The vector stuff covered in physics and math is slightly different (physics being easier), but once you learn physics vectors, math vectors are a cinch.</p>
<p>But if you can’t get a physics book, go here:

<p>At my school, the only AP Calculus offered is AB. I’m sure there are people in that class did did really good in Pre-Calculus.</p>
<p>can someone help me solve this problem:</p>
<p>LIM as X goes to
positive infinity:</p>
<h2>([sq. rt. of x+1] - [sq. rt. of x-1])X</h2>
<pre><code> (sq. rt. of Xsquared + 1)
</code></pre>
<p>Are you talking about the restrictions to the problem (what x cannot b)</p>
<p>what the limit of x is</p>
<p>If so:</p>
<h2>sq rt [x+1] - sq rt [x-1]x</h2>
<pre><code> X + 1
</code></pre>
<p><----(-1)-------------(1)--------></p>
<p>Think of the above as a number line (lol). The (-1) reprsents the undefined area of the equation and (1) represents a 0 of the problem. From here I would plug in -2 into the equation and instantly I recongize that sq rt [x+1] would be negative so anything less than -1 would not work (throw out the far left). Next I’d plug in 0 and again I reconigze that sq rt [x-1] would negative so I throw out the middle portion of the number line. Finally I test 2 and find that it does not yield any negative sq. roots. Therefore: x greater than or equal to 1.</p>
<p>I haven’t done any trig in Precalculus yet, just a review of Algebra, Algebra 2 so far.</p>
<p>limits r fun!
i love them
too bad theres only like 2 on the ap test</p>
