 4 If $\lim_{x\to\infty}(f(x)+f'(x))=L$ show that $\lim_{x\to\infty} f(x) = L$ and $\lim_{x\to\infty} f'(x) = 0$ 3 Prove that $f(x) = \left\{ \begin{array}{c} x^2, &x \le 1 \\ 3 - 2x, &x > 1 \end{array} \right.\;$ is continuous on $\mathbb R$… 1 If $\sum n^2 a_n^2<\infty$ then $\sum a_n$ is convergent. 0 Find limit when $\theta$ tends to $0$ of $\tan(\theta) /\theta$ 0 Why does $\sum_{n = 0}^\infty \frac{n}{2^n}$ converge to 2?
