Calculus 1: Limits

$\lim_{x \to 3} (2x + 5)$

$\lim_{t \rightarrow 1} \frac{t^3 - t}{t^2 - 1}$

$\lim_{h\rightarrow 0} \frac{(h-5)^2 - 25}{h}$

Use the squeeze theorem to prove the following important trigonometric limit

$\lim_{\theta\rightarrow 0} \frac{\sin(\theta)}{\theta} = 1$

$\lim_{x\rightarrow \infty}\frac{2x - 1}{x + 1}$

$\lim_{\rightarrow \infty}\sin\frac{1}{x}$

$\lim_{\theta\rightarrow 0} \frac{\sec{(2\theta)} \tan{(3 \theta)}}{5 \theta}$

$\lim_{x\rightarrow 0} \frac{\tan{x}}{x}$
