Question

What is the period of the sine funtion y = sin (2x) ?

Answer 1

Explanation:

You can "read" these information from the numbers in your equation:

y = 1 ⋅ sin (2x)

1 is the amplitude meaning that your function is oscillating between

+ 1 and − 1;

2 is used to evaluate the period as:

period = 2π/2 = π

so that one complete oscillation of your sine function is "squeezed" inside the interval 0 to π.

Answer 2

Answer: a
