(20 14? In the plane rectangular coordinate system xOy, as shown in the figure, it is known that the upper and lower vertices of the ellipse C: X24+Y2 = 1 are A and B, respectively, and the point P is within the ellipse. (1) Proof: We can know the points A (0, 1) and B (0, 1) from the topic ellipse C: X24+Y2 = 1.

Let P(x0, y0), then x0 ≠ 0 can be known from the topic.

The slope of the straight line AP k 1=y0 = Y0? 1x0, and the slope of PB is K2 = Y0+ 1x0.

And point p is on the ellipse, so x024+y02 = 1 (x0 ≠ 0), so there is k 1? k2=y0? 1x0? y0+ 1x0=y02? 1x02=? 14;

(2) Solution: From the problem, we can get that the equation of straight line AP is y- 1=k 1(x-0).

The equation of the straight line PB is y-(- 1) = K2 (x-0).

Shit, y 1=k 1xy=? 2. The solution was praised and trampled. What is your evaluation of this answer?

As shown in the figure, in the plane rectangular coordinate system xOy, point A is the left vertex of ellipse E: X2A2+Y2B2 = 1 (A > B > 0). 8520 12- 10-29 As shown in the plane rectangular coordinate system xoy, it is known that point A is the right vertex of the ellipse x2/9+2y2/9= 1, and point D (1, 0) and points P and B are on the ellipse./kloc Known ellipse c: x2/a2+y2/B2 = 1 (a > b > 0), passing point P( 1, 3/29201-02-01), as shown in the figure. +2z? =8, find the plane crossing the Z axis and the ellipsoid 120 16-04-23. In the plane rectangular coordinate system xoy, the ellipse C is x 2 4+y 2 =1(1). If a straight line intersects ellipse C at two different points M and N in the plane rectangular coordinate system xOy, 12020-03- 16, it is known that ellipse C: X2/A2+Y2/B2 = 1 (a > b > 0) passes through point P (/kloc-0). & gt recommended for you: F.context('cmsRight', [{'URL':'/d01373f082025aaf511aa256e9edab64034f1a07? x-BCE-process = image % 2f resize % 2Cm _ lfit % 2Cw _ 450% 2Ch _ 600% 2c limit _ 1% 2f quality % 2Cq _ 85% 2f format % 2Cf _ auto ', ' contractId':'A24KA00562 ',},{ ' URL ':/builder/bjh-activity/articlesTask? taskId = 1598082 & aside = 0 & footer = true & from = 0 ',' src ':'/203 FB 80 e 7 bec 54 e 773 ea 0680 ab 389 b 504 fc 26 a2d? x-BCE-process = image % 2f resize % 2Cm _ lfit % 2Cw _ 450% 2Ch _ 600% 2c limit _ 1% 2f quality % 2Cq _ 85% 2f format % 2Cf _ auto ',' contractId ':' ',},{ ' URL ':/s? word = % E6 % AC % A7 % E6 % B4 % B2 % E6 % 9D % AF & sa = searchpromo _ ozb _ zhidao _ tuijian ',' src ':'/3 BF 33 a 87 e 950352 AAF 5 df 4954 143 fbf2b 2 1 18 b6b? x-BCE-process = image % 2f resize % 2Cm _ lfit % 2Cw _ 450% 2Ch _ 600% 2c limit _ 1% 2f quality % 2Cq _ 85% 2f format % 2Cf _ auto ',' contractId ':' ',}]); Why is the cost of cancer treatment getting higher and higher?
