1. The problem statement, all variables and given/known data
Find the equations of the two tangents that can be drawn from
the point (5, 2) to the ellipse 2x2 + 7y2 = 14
2. Relevant equations
2x2 + 7y2 = 14
differentiating we get slope = -2x/7y
3. 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?:confused:
can someone please explain this?
x − y = 3 and x − 9y + 13 = 0.
puzzled i dont know how
