数学讲义翻译(英译汉)急
1。set denominator equal to zero to find the equation of the vertical asymptote(s)
2。a)set numerator equal to zero to get the x-intercept。
b)set x=0to find the y-intercept。
3。if there are common factors involving variables in the numerator and denominator,then there eill be points of discontinuity。
to find them,find the zeros of the common factors。
4。if the numerator and denominator are of the same degree,there will be a horzontal asymptote。
to get the equation fo that asymptote,divide the numerator and denominator bu the largest power of x and then check the value of the resulting function as x approaches infinity。
5。if the denominator is of higher degree,then the x axis is the horizontal asymptote。
6。if the denominator is one degree lower than the numerator,then there will be a slant asymptote 。
you can find ts equation bu doing the long division,and then considering the equation that results as x approaches infinity
。

to 的点找他们,找通常的因素零。 4。 如果分子和分母是相同的程度, 将会有 horzontal asymptote。to 当 x 接近无限大，拿那一个渐近线给相等 fo, 分开 x 的分子和分母 bu 最大力量然后检查产生的功能价值。
5。 如果分母是较高的程度,然后 x 轴是水平的渐近线。 6。 如果分母比分子低一度, 然后将会有一个倾斜的渐近线。你能找 ts 相等 bu 做长的区分,然后考虑产生如 x 的相等接近无限大 。
