<p>Do we need to know derivatives, etc in vector equations? What do we need to know, and can you please explain it to me? (I’m self-studying Calc BC and it isn’t in my textbook.)</p>
<p>not really. There is little chance of one being on the test</p>
<p>Don’t worry too much about vectors. All I know is when differentiating vectors in the form ai + bj, the derivative is da<em>i +db</em>j, and the same concept for integrating. You do have to know speed, which is sqrt((v1)^2+(v2)^2). Magnitude is v / |v|, and uh…</p>
