Sec 4] Graph<strong>in</strong>g Functions by Characteristic Po<strong>in</strong>ts 97<br />

It is convenient to tabulate the results of such an <strong>in</strong>vestigation (Table I),<br />

calculat<strong>in</strong>g also the ord<strong>in</strong>ates of the characteristic po<strong>in</strong>ts of the graph of the<br />

function. It will be noted that due to the oddness of the function r/, it is<br />

enough to calculate only for Jc^O; the left-hand half of the graph is constructed<br />

by the pr<strong>in</strong>c<strong>ipl</strong>e of odd symmetry.<br />

Table I<br />

e) Us<strong>in</strong>^ the results of the <strong>in</strong>vestigation, we construct the graph of the<br />

function (Fig 33).<br />
