##### How to use

*Enter* the formula for the *n*^{th} term
*a*_{n} (in terms of the variable
*n*) in the text input field
marked "n^{th} term =".
__Example__:
*a*_{n}=1/*n*!

*Click* the "Graph" button (this button also
refreshes the graph).

*To erase* the
text input field and set the starting value of *n*
to a default value, click the "Clear" button.

##### Examples

__Harmonic__:
*a*_{n} = 1/*n*,
start with *n*=1
(*diverges*)
__Alternating__:
*a*_{n} = (-1)^{n}/*n*,
start with *n*=1
(*converges*)

__p-Series__:
*a*_{n} = 1/*n*^{2},
start with *n*=1
(*converges*)

__Factorial__:
*a*_{n} = 1/*n*!,
start with *n*=0
(*converges*)

##### Other Notes

The graph shows the terms of the sequence
{*a*_{n}} in
red and partial sums of the series
*a*_{n}
(i.e. the terms of the sequence {*S*_{n}} where
*S*_{n}=*a*_{0}+*a*_{1}+...+*a*_{n})
in blue on the same set of axes.
