I have been trying to do that. However, I have not been able to find the intersection of the tangents and there is not intersection of the original functions.
Homework Statement
Is there anything special about the tangents to the curves xy=1 and (x^2) - (y^2) =1 at their point of intersection in the first quadrant.
The Attempt at a Solution
I know what the derivatives of both functions are and what they look like when graphed. But, I'm not...
