This app helps me so much, its basically like a calculator but more complex and at the same time easier to use - all you have to do is literally point the camera at the equation and normally solves it well! It is found according to the following: How to find vertical and horizontal asymptotes of rational function? To find a horizontal asymptote, compare the degrees of the polynomials in the numerator and denominator of the rational function. (There may be an oblique or "slant" asymptote or something related. Solution:Since the largest degree in both the numerator and denominator is 1, then we consider the coefficient ofx. There are three types: horizontal, vertical and oblique: The direction can also be negative: The curve can approach from any side (such as from above or below for a horizontal asymptote), If the degree of the numerator is exactly one more than the degree of the denominator, then the graph of the rational function will be roughly a sloping line with some complicated parts in the middle. This function has a horizontal asymptote at y = 2 on both . New user? So this app really helps me. In order to calculate the horizontal asymptotes, the point of consideration is the degrees of both the numerator and the denominator of the given function. Figure 4.6.3: The graph of f(x) = (cosx) / x + 1 crosses its horizontal asymptote y = 1 an infinite number of times. Except for the breaks at the vertical asymptotes, the graph should be a nice smooth curve with no sharp corners.
