I seem to remember Laz's technique from horiz/vert asymptotes - bit of a pain for an oblique aymptote though. The long div method is better if ur going for the eqn I think. I think that's what Pender's book recommends in that damn curve sketching menu chapter.Originally posted by Weisy
Laz's example is v. good. I never knew about dividing through by the highest value in the denominator either!
To find oblique asymptotes alternatively you can divide the numerator by the denominator (since the numerator has to have a greater power if the thing has an oblique asymptote) using long division.
I hate long division though.
