Self study calculus AB

<p>So basically last semester my teacher messed up on teaching pre calculus meaning we used a uselss small blue book filled with vectors.</p>

<p>So we moved onto ap calc A this semester, but i have no fundementals in pre calculus</p>

<p>Is there any review book or any book thatt is easy to understand for me to learn AP calculus AB and also solidify my pre calculus fundementals???</p>

<p>the only thing important in precalculus is knowing trigonometry for calculus AB.</p>

<p>I used PR to help me do well on the AP Calculus AB exam.</p>
