## Section16.14Polar Coordinates
##### Polar Coordinates.
When graphing in two-dimensions, the most common way we identify points in the plane is with the use of rectangular coordinates ā i.e. by the ordered pair $(x,y)$ (or whatever variables are in use). In this section we talk about an alternate strategy for ide... |

## Precalculus (6th Edition) Blitzer
The simplified solution is $\frac{1}{x}-\frac{1}{x+2}$ and the sum is $\frac{100}{101}$.
Let us consider the rational expression. \begin{align} & \frac{2}{x\left( x+2 \right)}=\frac{A}{x}+\frac{B}{x+2} \\ & =\frac{A\left( x+2 \right)+Bx}{x\left( x+2 \right)} \end{align} $2=A\left( ... |

How do you identify all asymptotes or holes for f(x)=(x^2+3x-4)/(2x^2+10x+8)?
Oct 30, 2016
vertical asymptote at x = - 1
horizontal asymptote at $y = \frac{1}{2}$
hole at x = -4
Explanation:
The first step is to factorise the numerator/denominator of f(x).
$f \left(x\right) = \frac{{x}^{2} + 3 x - 4}{2 {x}^{2} + 1... |
