<p>Single-variable calculus part one is the study of limits, derivatives, and integrals and their applications. This is AP Calculus AB. Single-variable calculus part two is the study of indeterminate forms and L’Hopital’s Rule, advanced trigonometric substitution, improper integrals, sequences, and series. This is AP Calculus BC.</p>
<p>I’m not too big of a fan of the word precalculus. I think it’s very misleading. Most of the time it’s just a fancier way of saying trigonometry.</p>
<p>Two users here have taken precalculus classes where they’ve learned limits, derivatives, and integrals. Well then, that’s not PREcalculus.</p>
