Question
The maximum distance of the point (k, 0) from the curve 2x2 + y2 - 2x = 0 is equal to
Options
A.
B.
C.
D.
Solution
Let d be distance between (k, 0)
and any point (x, y) on curve.
d =
d =
(∵ y2 = 2x - 2x2).
Maximum d =
Maximum d =
and any point (x, y) on curve.
d =
d =
(∵ y2 = 2x - 2x2).Maximum d =
Maximum d =
