units, the only real root of the equation. 2. Given y^—75y=250, to find the values of j by construction. When the co-efficients are large, alarge figure is required ; but to avoidthis inconvenience, we reduce the co-efficients, as shown in Chap. II, Sec. I. Thus put y=nz. Then the equation becomes… … CURVES AND LINES. 116 Now take n—5, then we have In this last equation the co-efficients are sufficiently small toapply to a construction. Put 4__4a=—3, and 85=2. Whence a=lf and b=\. These values of a and b designate the point D for the centerof the circle. DA is the radius. The circle cuts the…
