Question

What is the period of the sinusoidal function

Answer 1

The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.

From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units

Therefore, 10 units is the right answer.

Answer 2

• 10

Explanation:

• Period is the distance between two consecutive maximum points, or two consecutive minimum points.

On the given graph the period is the distance between maximum points -7 and 3:

• 3 - (-7) = 10
