The formula: $$\lim_{n\rightarrow\infty} q^n = 0$$. Some sentence. $$\text{ക}$$ $${\displaystyle \frac{\text{ച}}{\angle 4\text{ത്ര}^3} = } $$ $$n$$ n, $$X$$ X

$$z = r^\frac{1}{n}n \cdot \operatorname{cis}\tfrac{\varphi}{n}$$

$$\bar{z} = \overline{z}$$.

$$\Coppa, \coppa, \Koppa, \koppa, \Stigma, \stigma, \S, \P$$

$\bar{z} = \overline{z}$.

$$xyx \text{äüub}$$ $$\begin{align} Q_1 &= U_1\\ C &= a \cdot Q_1 + U_2\\ Q_2 &= c \cdot C + d \cdot Q_1 + U_3\\ S &= b \cdot C + e \cdot Q_2 + U_4, \end{align}$$
