Ex. 1. Take the equation y = sni X. We consider the angle x expressed in circular measure, and lay offfirst the distance, 7r = 3.1416, and its multiples. Each division of the LOCI. 29 axis we then subdivide into convenient intervals, say sixtlis, and obtainthus upon tlie x-axis the points It Tt 7t… … It is necessary to plot only that portion of the curve between x = 0and X = TT. For sin (x ± tt) = — sin x, and sin (x ± 2;r) = sin x. Hencethe curve y = sin x is composed of an indefinite number of arches extend-ing both to the left and to the right, the arches being alternately aboveand below the…
