ine a set of oblique axes, origin at center, to which, whenthe hyperbola is referred, its equation takes the form xij — c. 44. Determine origin and direction of a set of oblique axes to which,when the parabola is referred, its equation has the same form as thecommon equation of the parabola. 45.… … Art. 36.—Tolau Cooudinates of a Point In the plane, suppose the point A and the straight line AXthrough A fixed.
