Упражнение:
$$\lim\limits_{x \to 0}{\frac{\cos x — \cos 2x}{1 — \cos x}}$$
Я разместил свое решение ниже, однако, если есть более элегантные подходы, не стесняйтесь включать свои собственные решения. 2(x)-1$$ 92(x)=(1-\cos(x))(2\cos(x)+1)$$
Если мы вычислим напрямую, то получим дробь $\frac{0}{0}$. Итак, используя правило Лопиталя:
$$
\lim_{x \rightarrow 0} \frac{\cos x — \cos 2x}{1-\cos x}
«=»
\lim_{x \rightarrow 0} \frac{-\sin x + 2\sin 2x}{\sin x}
$$
Теперь, если мы еще раз вычислим напрямую, мы получим дробь $\frac{0}{0}$.
