To compare the results from the series with those of the original function, load

these functions into the PLOT – FUNCTION input form („ñ,

simultaneously if using RPN mode):

Change the limits of the Plot Window („ò) as follows:

Press the soft-menu keys @ERASE @DRAW to produce the plot:

Notice that the series, with 5 terms, “hugs” the graph of the function very

closely in the interval 0 to 2 (i.e., through the period T = 2). You can also

notice a periodicity in the graph of the series. This periodicity is easy to

visualize by expanding the horizontal range of the plot to (-0.5,4):
