Area A and circumference C of circle given
radius R or diameter D
 |
D = 2 * R
A = Pi * R2
A = Pi * D2 / 4
C = Pi * D
C = Pi * 2 * R

Intersection of two lines
basic formula of line : y = mx + b
 |
at intersection we have
y1 = y2
m1 * x + b1 = m2 * x + b2
x (m1 - m2) = b2 - b1
x =
(b2 - b1) / (m1 - m2)
y =
m1 * x + b1
! uncomputable if m2
= m1
