△CMP is similar to △APN, because a pair of vertex angles are equal, so it is only necessary that angle C or angle M is a right angle. (1) If the angle C is a right angle, let C be perpendicular to MN and H, and the square of CH is equal to MH multiplied by pH ... You set the abscissa of P, and the ordinate is displayed, and the coordinate of M is also represented by the letter of the abscissa of P, then you can use the previous equation to find the letter of the abscissa of P.

(2) If the angle m is a right angle, then CM is perpendicular to MN, that is to say, the vertical coordinates of m and c are the same, both of which are 6. Bring the ordinate 6 into the analytical formula and calculate the abscissa as 0.
