We now require a third line which shall pass through thesame point of intersection and form an angle with the axis ofX (the tangent of which may be… … Let PN represent the linecorresponding to equation (1)»PM the line whose equation is(2), and PR the line required. Now the position or inclina-tion of PN to AX depends en-tirely on the value of a, and theinclination of Pilf depends on a\and all are entirely independentof the position of the point…
