An ellipse , centred at the origin , has major axis 2a . If it passes through a given `(x_(1), y_(1))` , show that its
eccentricity is `sqrt((x_(1)^(2) + y_(1)^(2) - a^(2))/(x_(1)^(2) - a^(2)))`

Text Solution

Verified by Experts

The correct Answer is:
`therefore e = sqrt((x_(1)^(2) + y_(1)^(2) - a^(2))/(x_(1)^(2) - a^(2)))`
