Tomorrow I go take a Math Placement Test for college. I hate math so much, but I can do really well as long as I'm prepared. With whatever formulas I get I'm going to prep, myself. Please be serious. I graduated high school in 2005 and so I haven't done anything remotely math related in a while (other than money counting)
THANKS BUNCHES IN ADVANCE : )

some common formulae i am listing below hope they will do some help.
area os square=a^2
area of rectangle=lxb
area of circle=pi(r)^2
volume of cube=a^3
volume of cuboid=lxbxh
volume of cylinder=pi(r)^2 h
volume of cone=1/3 (pi) (r)^2h
some algebraic identities...........
a^2- b^2=(a-b)(a+b)
a^3-b^3=(a-b)(a^2+ab+b^2)
a^3+b^3=(a+b)(a^2-ab+b^2)
some trigonometry formulae........
sin(theta)=p/h
cos(theta)=b/h
tan(theta)=p/b
cosec(theta)=h/p
sec((theta)=h/b
cot(theta)=b/p
{here p= perpendicular or side oppoite to angle theta)
b= base , the side containing angle theta
h=hypotenuse, biggest side opposite to 90 degree angle.}

Quad formula above is incorrect (see http://en.wikipedia.org/wiki/Quadratic_formula ). For a list of basic formulas, I suggest you look at http://campus.northpark.edu/math/PreCalculus/formulas.html. Review of a basic textbook would also help you.

Frankly, the question itself is offensive but try the following site:

Or do what I did. Google "math formula sheet"

Good luck.

I don't have any formulas for you, but good luck on your test. You've got your work cut out for you between now and then.

Trigonometry:
Sine Θ = Opp./ Hyp.
Cosine Θ = Adj../Hyp.
Tangent Θ = Opp./ Adj.

Area of circle: π r²
Cir. of circle: 2 π r.
