- Started with
\[\left(\frac{1}{x + 1} - \frac{2}{x}\right) + \frac{1}{x - 1}\]
8.1
- Applied taylor to get
\[\left(\frac{1}{x + 1} - \frac{2}{x}\right) + \frac{1}{x - 1} \leadsto 2 \cdot \frac{1}{{x}^{5}} + \left(2 \cdot \frac{1}{{x}^{7}} + 2 \cdot \frac{1}{{x}^{3}}\right)\]
0.7
- Taylor expanded around inf to get
\[\color{red}{2 \cdot \frac{1}{{x}^{5}} + \left(2 \cdot \frac{1}{{x}^{7}} + 2 \cdot \frac{1}{{x}^{3}}\right)} \leadsto \color{blue}{2 \cdot \frac{1}{{x}^{5}} + \left(2 \cdot \frac{1}{{x}^{7}} + 2 \cdot \frac{1}{{x}^{3}}\right)}\]
0.7
- Applied simplify to get
\[\color{red}{2 \cdot \frac{1}{{x}^{5}} + \left(2 \cdot \frac{1}{{x}^{7}} + 2 \cdot \frac{1}{{x}^{3}}\right)} \leadsto \color{blue}{\left(\frac{2}{{x}^{7}} + \frac{2}{{x}^3}\right) + \frac{2}{{x}^{5}}}\]
0.8
- Using strategy
rm 0.8
- Applied cube-mult to get
\[\left(\frac{2}{{x}^{7}} + \frac{2}{\color{red}{{x}^3}}\right) + \frac{2}{{x}^{5}} \leadsto \left(\frac{2}{{x}^{7}} + \frac{2}{\color{blue}{x \cdot \left(x \cdot x\right)}}\right) + \frac{2}{{x}^{5}}\]
0.8
- Applied associate-/r* to get
\[\left(\frac{2}{{x}^{7}} + \color{red}{\frac{2}{x \cdot \left(x \cdot x\right)}}\right) + \frac{2}{{x}^{5}} \leadsto \left(\frac{2}{{x}^{7}} + \color{blue}{\frac{\frac{2}{x}}{x \cdot x}}\right) + \frac{2}{{x}^{5}}\]
