    hi

    ive made a mistake in a question and i think i know why but could someone confirm?

    i assumed, for what reason im not too sure, that the gradient of the normal at any point P on the hyperbola is the same as the gradient of the point where the normal again crosses the hyperbola. is this assumption right or wrong?

    It's wrong. The normal could cross at a very shallow angle and isn't necessarily a normal at the other point.

    That's the worst mistake I've ever seen.








    Edit: apologies, I thought you were after hyperbole.

    The gradient of the curve at P, and the point where the normal (at P) again meets the curve will not in general be the same. A rough sketch should tell you that.

    you don't need the specific question, my question is not about it, but is a general one regarding all hyperbolae

    hyperbolae = plural of hyperbola

    hyperbole (pronounced the same) = exaggeration
