Homework Statement
Find the equations of the two tangents that can be drawn from
the point (5, 2) to the ellipse 2x2 + 7y2 = 14
Homework Equations
2x2 + 7y2 = 14
differentiating we get slope = -2x/7y
The Attempt at a Solution
y = slope(x)+c
y = -2x2/7y +c
when we plug in x and y we get c=39/7
so 5x+7y=39 is coming as answer
but it seems to be wrong.the questions says there has to be two tangents but how?
can someone please explain this?
x − y = 3 and x − 9y + 13 = 0.
puzzled i don't know how
