I read the explanation on horizontal asymptotic but was wondering if there was a better way of finding out the asymptotic without observing a graph when the power of the numerator is smaller than the denominator.

So if RL is "Roof Load", W is "width of the bay window's opening in the wall", D is "depth of the bay window, or how far the window sticks out past the rest of the wall", and P is "the pitch angle of the roof, covering the two-floor building, where the bay window i...

You can learn how to add fractions here and here. Before you try the problem, do at least 2 or 3 lessons from the links. Then do the common denominator (or LCM) of 8 and 7 (its 56) to get 35/56 and 16/56. Then add, etc.
