How to use
The text input fields can accept a wide variety of expressions to represent functions, and the buttons under the graph allow various manipulations of the graph coordinates.
Examples
Harmonic:
an = 1/n
start with n=1   
diverges
Alternating:
an = (-1)n/n
start with n=1   
converges
p-Series:
an = 1/n2
start with n=1   
converges
Factorial:
an = 1/n!
start with n=0
converges

Other Notes
The graph shows the terms of the sequence {an} in red and partial sums of the series ∑ an (i.e. the terms of the sequence {Sn} where Sn=a0+a1+...+an) in blue on the same set of axes.
