Question

Find the amplitude of the sine curve shown below.

Answer 1

ANSWER

The amplitude is

`4` units.

Step-by-step explanation

The
`<b>amplitude` is the measure of the the height from the center line to the peak or the trough of the given sine graph.


`amplitude = |4 - 0| = 4`

Or

We can also measure from the lowest height up to the highest height and divide by two to get the amplitude.


`amplitude = ( |4 - - 4| )/(2)`


`amplitude = ( 8 )/(2) = 4`

Answer 2

The amplitude of a sine curve is the largest distance between the base line and the highest peak.

The baseline is y = 0 in this case, and the highest point reached is 4, so the amplitude is 4.
