Build the necessary mathematical information to conclude the MAP
coordinate interpolation function. Including geometry and trigonometry.

You have a pipe that is 2 meters in diameter. How wide would the pipe be
if you flattened the pipe? I can't remember why I once wanted to know this
but I came up with the following: width = (diameter * pi) / 2.

2^x=8|log_2 8=x

A natural logarithm (usually written as ln) is the logarithm of a number
to the base of _e_. Thus, log_e x. e (Euler's constant) is an irrational
number (much like pi) that is built through the following sum:
 e = 1/0! + 1/1! + 1/2! + 1/3! + 1/4!.... 
   = 2.71828182845904523536028747135266..

the logarithm of 6 to the base 2 = x (i.e. 2^x = 6)
