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.
