Find the amplitude and period of the following functions.

1. y = (-1/2)cos(x/2)

2. y = - sin (xpi)

Question 1

Let A = amplitude

A = |-1/2|

A = 1/2

Let P = period

Let B = coefficient of x

P = 2pi/B

P = 2pi/(1/2)

P = 4pi

Yes?

Question 2

A = |-1|

A = 1

P = 2pi/B

P = 2pi/pi

P = 2

Yes?
