<p>Anyone know the formulas that are on most of the ACT's.
Formulas that we have to knwo for the math?</p>
<p>For math, I would say:</p>
<p>Distance
Midpoint
Slope
Quadratic
Pythagorean
Volume
Area (Rectangle, triangle, circle)
Circumference
Perimeter</p>
<p>I think that is it. You might want to know the 30-60-90 and 45-45-90 triangles.</p>
<p>Yea, what bball7057 said.</p>
<p>In addition, I'd study the formula sheet that's on the 1st page of every math section on the SAT. A lot of the formulas on that can be applied on both the ACT/SAT.</p>
