I keep getting “Standard limit” questions wrong in Limits & Continuity. What's the trap?
evaluating it as 0/0 and stopping.
The usual trap: evaluating it as 0/0 and stopping. How to avoid it: 0/0 is indeterminate — use standard limits or L'Hôpital's rule. Go back to the definition — lim(x→0) sin x / x = 1 is a key result used everywhere.
