Question

At \( t = 0 \), the function \( f(t) = \sin \frac{t}{t} \) has

• A. a minimum
• B. a discontinuity
• C. a point of inflection
• D. a maximum

Hint:

When dealing with limits involving division by zero, check if the function approaches a finite value or if a discontinuity exists.

Answer 1

The Correct Option is B

At \( t = 0 \), the function \( f(t) = \sin \frac{t}{t} \) does not have a well-defined value, indicating a discontinuity at that point.
