#pi# is an irrational number.

It is not expressible as a fraction, terminating or repeating decimal.

#pi# is expressible as the sum of an infinite series.

As an illustration:

#pi = 4 * tan^(-1)(1) = 4 * (1-1/3+1/5-1/7+1/9-1/11+...)#

There are some useful rational approximations for #pi#.

For example #22/7 = 3.dot(1)4285dot(7)# and the much more accurate #355/113 ~~ 3.1415929#

or, naturally, approximations in decimal:

#pi ~~ 3.141592653589793238462643383279502884197#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
