- In a computer program I am writing, I need to intersect two
- arbitrarily oriented hyperbolas. These hyperbolas are defined by the
- following two equations:
-
- a_1*x^2 + b_1*x*y + c_1*y^2 + d_1*x + e_1*y + f_1 = 0
- a_2*x^2 + b_2*x*y + c_2*y^2 + d_2*x + e_2*y + f_2 = 0
-
- where the two discriminants, b_1^2 - 4*a_1*c_1 and b_2^2 - 4*a_2*c_2,
- are positive. I have been unable to analytically solve for the
- intersection points.
-
- Any help would be greatly appreciated.
