A company is studying the temperature of a chemical reaction. The temperature T(t) is given by the function T(t) = e^(-2t) sin(2πt). Which of the following statements about the temperature is true?

A.C) The temperature approaches 0 as time approaches ∞.
B.D) The temperature oscillates with increasing amplitude as time approaches ∞.
C.B) The temperature approaches a non-zero constant as time approaches ∞.
D.A) The temperature approaches ∞ as time approaches ∞.

Explanation

Core Concept

This question tests the student's understanding of limits and the behavior of functions over time. The temperature approaches 0 as time approaches ∞ due to the e^(-2t) term. Option A is incorrect because the temperature approaches 0, not ∞. Option B is incorrect because the temperature approaches 0, not a non-zero constant. Option D is incorrect because the temperature oscillates with decreasing amplitude, not increasing amplitude.

Correct Answer

AC) The temperature approaches 0 as time approaches ∞.
