Try this true/false problem from TIFR 2013 Problem 12 based on Limit.
Question: TIFR 2013 problem 12
True/False?
$$ \lim_{x\to 0} \frac{sin(x^2)}{x^2}sin(\frac{1}{x}) = 1$$
Discussion:
As \(x\) goes to zero, \(x^2\) also goes to zero, and consequently, since $$ \lim_{y\to 0} \frac{sin(y)}{y}=1 $$ we have $$ \lim_{x\to 0} \frac{sin(x^2)}{x^2}= 1$$. If the statement were true, then \(\lim_{x\to 0}sin(\frac{1}{x}) = 1\), which is false. In fact, \(\lim_{x\to 0}sin(\frac{1}{x}) \) does not exist.
So the statement is False.
