significance of this operationwiU be readily seen by constructing a few parabolas onthe same axis, giving to m slightly differing values. Theconsecutive intersections, a, h, c, a, h, c, etc., will ev-idently approach the two straight hues AM, AMasthe difference between the consecutive values of m… … Fig. 164. 154: PROPERTIES OF PLANE LOCI. Ex. 2. Find the envelope oi y = ax -\ , a being the parameter. Construct a figure illustrating the result. The envelope is y^ = 4m^. Ex. 3. A line of fixed length slides between two fixed lines at rightangles to each other ; required the envelope.…
