transform tothis point as origin. The equations of transformation are(by [20]) Substituting these values, the equation becomes y- = 2nioc. [34] From this equation we see that the curve passes throughthe origin; that it is symmetrical with respect to theX-axis ; that it is real only to the right of… … But, for the study of the distant points, polar coordinatesare better adapted. Transforming to pohar coordinates witli 0 as origin, equa-tion [34] becomes _ 2 m cos 9^~ sin2 6> When 0 = 0, p is infinite,and the curve, therefore,does not cut the JT-axisa second time. But ifwe give to 6 any…
