Trigonometry: Trigonometric Functions Practice MCQ

Question Statement:

Which of the given functions has the greatest amplitude?

\frac{sin2(π + 7)}{3}

\sin (x + 3)

\sin (4 x)

\frac{1}{2} \sin (4 x)

2 \sin (x)

Explanation:

Correct Answer: E

The amplitude of a function is the amount by which the graph of the function travels above and below its midline. When graphing a sine function, the value of the amplitude is equivalent to the value of the coefficient of the sine. Similarly, the coefficient associated with the x-value is related to the function's period. The largest coefficient associated with the sine in the provided functions is 2; therefore the correct answer is 2sin(x).

The amplitude is dictated by the coefficient of the trigonometric function. In this case, all of the other functions have a coefficient of one or one-half.
