The plot command can be used to graph a sequence whose terms are given by a function. The syntax is
plot( 
, n=j..k, style = point);
For `` " put in the function that gives the terms of the sequence; j is the number of the first term to be plotted; k is the number of the last term to be plotted. For example, to plot the first 25 terms of 
, use
> plot(ln(n)/sqrt(n), n=1..25, style = point);
In the exercises you will need the Maple sum command. The syntax is
> sum('f','k' = m .. n);
for instance, to find 
for 
use
> sum('1/k', 'k' = 1..40);
Note that the expression for 
and the k in the range statement are enclosed in apostrophes.
Reminder: evalf(") can be used to get a decimal approximation to a numerical expression that has just been given as output.
