You know the first question, the second question, the center of the circle is (1, 0), r= 1, a=2, b= root number 3, let n (0, y 1), m (0, y), and let p (x0, y).

P satisfies the elliptic equation, an equation, lists lpm and Lpn equations, and the distance from the center of the circle to each one is 1.

∫MN is on the y axis, which is convenient for calculation. Find the distance d from p to it, s =1/2 | Mn | d.

The problem is not difficult, do it with your heart, and the curve is a routine. Oil; Fuel filling; Make greater efforts
