55. The equations of the 2 graphs shown below are y1(t) = a1 sin(b1t) and y2(t) = a2 cos(b2t), where the constants b1 and b2 are both positive real numbers.

Which of the following statements is true of the constants a1 and a2 ?

Answer and Explanation

Your Answer is

Correct Answer is B

Explanation

The amplitude of y1 is larger than that of y2, so a1>a2>0 chooses B
