Find the LCD of 2(x+3)(x+5) and x(x+3)(x−1) . 2. Determine the LCD of 4(x+4)(x−9) and 2x(x+1)(x−9) . 3. For the following rational expressions, find the LCD: 3(x+2)(x+6) and 5x(x−8)(x−3) . 4. For the given rational expressions, de...
TODO SymPy Rationals are used here because floor, ceil with sympy expressions have some nonstandard behavior (not to return int), and QQ is not very happy about it. """ inf = floor(a) sup = ceiling(b) assert inf < sup diff = sup - inf if diff > 1: return (inf + sup) // ...

Some words and expressions in the workbook were revised based on the feedback from the participants. The program was considered to not cause any inconvenience or side effects to the participants. A single-arm pre–post test also revealed the potential to enhance benefit finding. Therefore, we ...
1. 如果n<mn<m,那么 X 轴,即y=0y=0为水平渐近线。 2. 如果n=mn=m,那么水平渐近线为直线y=aby=ab。 3. 如果n>mn>m,那么水平渐近线不存在(存在一条斜渐近线)。 求nn和mm。 n=1n=1 m=2m=2 因为n<mn<m,所以 x 轴、y=0y=0是水平渐近线。
