<p>Well, I am new to this forum and was hoping some of you intelligent people would like to help me gather a list of math equations needed for the ACT.
Like slope intercept form, ax^2+bx+c, SOHCAHTOA, etc.</p>
<p>Thanks guys and gals!!</p>
<p>y=mx + b
D=2r
C=Pie<em>D
Area Circle=Pie</em>R^2
30-60-90 triangle (1,sqrt3,2)
law of sines a/SINA=b/SinB=c/SInC (A is angle, a is side)
law of cosines a^2=b^2+c^2-2bcCOSA
arc length= theta/360 * circumference
area of sector= theta/360 * area
Those are some easy ones, you should be able to find the rest in a book</p>
<p>thanks...anyone else have any suggestions?</p>
