<p>What formulas, if any, are given on the test? I think, but not too sure, they give us the special case right triangles? As for the rest, we have to memorize and know the half angle formulas right?</p>
<p>Barrons only provides some surface and volume formulas before each of its practice tests. I imagine that they copied that info from the actual tests. </p>
<p>P.S. You have to be pretty naive to think that they would provide you with some trig or triangle formulas. (Look closer maybe the answer key will be attached as well . . . )</p>
<p>I’m going with what Barron’s provides.</p>
<p>Also, in the newest edition, they deleted the half angle and summation of angles. Must not be on the SAT 2 or something…</p>
