    Hyperbola a^2 + b^2 = c^2
    Why, in a Hyperbola, does a^2 + b^2 = c^2 ? Why do the 2 C's equal?


    Thanks!

    Here's why. It's a property of hyperbolas.

    I don't see two Cs in your equation
    and why are we talking about hyperbolas but using the equation for, and drawing pictures of, a circle? *confused!*

    Go here for the explanations of the hyperbola. It can be found in most algebra and calc books. A does not necessarly equal b.

    I guess the OP image didn't come across when I saw this the other day! Makes more sense now :)
