<p>What are the prerequisites for starting Calc AB?</p>
<p>Are there any concepts from Pre-Cal that I need to know by heart? I would appreciate any advice and tips too!</p>
<p>Be comfortable with basic trig identities - things like csc(x) = 1/sin(x), sin^2(x) + cos^2(x) = 1, and maybe sin(2x) = 2sin(x)cos(x). And know your unit circle.</p>
<p>Really, besides that…you don’t need anything from precalc that I can think of. Just don’t make dumb algebra mistakes and you’ll absolutely kill the class and exam.</p>
<p>Agreed with above - as long as you know Alg 2 / Trig pretty well, you’ll be fine.</p>
<p>Is it really a completely different way of looking at math? I’ve always had mixed math skills; I liked algebra and did pretty well in Alg2/Trig, but Geometry was awful for me. Precalc was a mixed bag.</p>
<p>Calculus is easy… Its the algebra that people mess up on! 
Geometry makes a return to an extent… sorry to inform you joshmay94. Well actually… Calculus is the culmination of your entire mathematical life. As they say… Calculus is the Dessert of Mathematics!</p>
<p>Ha, more like the DESERT of math to me :)</p>
<p>Well, geometry old nemesis, here we go again.</p>
