Question

from the point (lambda 3) tangnts drawn to (x^2)/9 (y^2)/4

Answer 1

The parameter will be (x – x1)^2 + (y – y1)^2 + λL = 0, since there is no L in the question,

X1 = x^2/9

Y1 = y^2/4

the equation of the family,

y – y1 = m (x – x1) at (x1, y1)

if x-axis is paraller to x1, y1

(x – x1)2 + (y – y1)2 + K(y – y1) = 0
