Additional Math Stuff:
Geometry:
 Sin A = opp/ hyp
  Cos A = adj./hyp.
  Tan A = opp/adj
a^2 + b^2 = c^2
Triangle Trig.
Two-D Formulas
Sum of angle measure of n-gons = (n-2)*180
Regular n-gons:
p=ns
Quad. sum of angle measures = 360
Triangles:
sum of angle measures = 180
p = a + b + c
A = 1/2 b h
A = SQRT(s(s-a)(s-b)(s-c)) where s=1/2 p
Kites: p = 2a + 2b
A = 1/2 d(1)d(2)
Trap.: A=1/2(b(1) +b(2)) h

Parallelogram:       Squares:
p=2a + 2b             p = 4s
A= bh                   A= s^2
