 According to the session, let us understand the following question which says the points on the curve 9y square is equal to x cube where the normal to the curve makes equal intercepts with the axles are a, 4 and plus minus 8 by 3, b, 4 and minus 8 by 3, 3 minus 3 by 8 and b plus minus 4 and 3 by 8. Now let us proceed on to the solution, let x1, y1 be the point on the curve x1 cube differentiating both the sides we get
