nveniently to find anumber of points of the locusof an equation, make y an ex-plicit function of x; thus y =l (x -\- 3)) then giving to x anumber of equidistant consecu-tive values, as 0, 1, 2, 3, 4, 5,the corresponding values of y,1-J-, 2, 21 3, 31 4 are readilyfound, and points P, P, P… … INDETERMINATE EQUATIONS AND FUNCTIONS. 19 -.JP structed lie on one straight line, as in the figure. This straightline is in fact the locus of the equation, but neither these points,nor any number of others which might be constructed with inter-mediate values of x, properly speaking, constitute the…
