Oblique Asymptotes
I was wondering if anybody had a simple rule for how to find the oblique asymptote of an equation.

To find them i basically just graph the equation and then draw a tangent to the line, thats easiest for me. You can try that or canceling terms out (this works for some reason) like if its (x^2+5x)/(x+2) the x cancels out one of the x's in x^2 and the 2 brings the 5 to 2. This works since when i draw a tangent line to that equation i get ~1x+~3
You can also use "propFrac" on your calculator to divide the numerator by the denominator. You then consider the remainder negligible, and what's left will be the slant/parabolic/etc asymptote.
