INTERSECTING SCALES 115 Thus all lines through P have a, h satisfying the equation y a 0 If then a; is a solution of the equation ^+^f' + l=0, a 0 we have A{x) = —^, B{x) = —t], as in the case of rectangular coordinates. … We see, therefore, that the general method is just as simple as the method with perpendicular scales. With oblique coordinates the plotting will as a rule be more difficult owing to the non-availability of rhombussed paper : in practice we may use the method sketched in §§ 49-50, to be dealt with…
