Find the equations of tangents to xy = 3 parallel to y + 3x = 4. What is the distance between these tangents.

Hello.

How exactly do I find out the points on which the tangents touch the hyperbola?

Thank you.

Dear Sudharaka

What's the point of differentiating the equ. of the hyperbola?

Isn't that only when you need to find the gradient of the tangents? - Apr 9th 2010, 10:27 PMSudharaka
