we find the followingtable of values, and points in the locus : When£e = l, y=±z v24 = ±: 4.9 nearly ; and we have points (1, 4.9) and (1,—4.9); « £>;==2, y.-^=fc ^^21 ==h4.6 nearly; (2, 4.6) and (2,—4.6); * 05=^3, y=rfc^l6 = =fc4 « (3, 4,) and (3,--4); ** a = 4, 2/=.rt:v/9 =±3 . « (4, 3,) and… … Constructing the points thus determinedthey are found to be in the circumference of acircle whose radius is 5, and which is sym-metrical with the axes, as in Fig. 12. It isalso to be observed that any values of x,fractional as well as integral, between thelimits x = 5, and x = — 5, give values for…
