<p>I am cramming tonight and my only true problem on the test will be math. What are some of the most helpful formulas to know for the test?</p>
<p>quadratic formula
distance formula
circle formula
midpoint formula</p>
<p>(x-y)(x-y)</p>
<p>(x+y)(x+y)</p>
<p>(x+y)(x-y)</p>
<p>can someone put up geometry formulas like those with circles?</p>
<p>law of sines is the most important IMO
(sin a)/A = (sin b)/B = (sin c)/C</p>
<p>it's on there soooooo many times (at least when I took it in december)</p>
<p>cramming is the WRONGGGG thing to do! omg u can make your score go down by cramming...it really won't help! but if u really want help and dont have any practice books go to number2.com</p>
<p>I dunno, I found the formula for the area of an equilateral triangle pretty useful.</p>
<p>I found that graphing saved me from even thinking about the quadratic and distance formula.</p>
