According to the meaning of the question: x12+4y12 =16x12+Y22 =16? y22=4y 12，

∫y 1, y2 is the same symbol, ∴y2=2y 1,

Let C(x3, y3) and D(x3, y4), and y4=2y3 can be obtained by the same method.

∴|AB|=|y 1|,|CD|=|y3|，

Multiply x2+4y2 = 16y = KX+ 1? (4k2+1) x2+8kx-12 = 0, and △ > 0 holds.

So x 1+x3 =? 8k4k2+ 1，x 1x3=？ 124k2+ 1，

∵A and C are on both sides of the X axis, ∴ Y 1Y3 < 0.

∴(kx 1+ 1)(kx3+ 1)=k2x 1x3+k(x 1+x3)+ 1= 1？ 16k24k2+ 1 1 16，

∴|||| AB |-| CD |||| =|| y/kloc-0 /|||| y3 | = | y1+y3 | = k (x1+x3)+2 | = 2 What's your comment on this answer?
