Question

What is the period of the function y=2sin x?

Answer 1

The period = 2pi / 1 ( because the coefficient of x = 1)

Its option B

Answer 2

period of the given function is 2π

B is the correct option.

Explanation:

The given function is y = 2sin x

Compare this equation with y = AsinBx+C

A = 2

B = 1

C = 0

The period is given by the formula

`P=(2\pi)/(B)`

Substituting the value of B

`P=(2\pi)/(1)\\\\P=2\pi`

Therefore, the period of the given function is 2π

B is the correct option.
