Here we study the plots of Figures 4.20 and 4.22.

(a). Plot the point*( 1,1). Plot the function

(b). Plot the points (1,1), (2, ), and (3, ¼), then plot  from x = 0 to x = 3.

(c). Can you produce the other plots in Figure 4.20?

(d). Plot the points , where n goes from -4 to +4 in integral steps.

(9 points). Then plot from X = -40 to x = +40 the function with nine terms, each of the form

 where n goes from —4 to +4 in integral steps.

(e). Can you produce the other plots in Figure 4.227
