Question

Find the amplitude and period of y= -5 sin (5x)

Answer 1

amplitude: 5

period:
`(5)/(2\pi )`

Explanation:

The amplitude is the height of the sine wave. It is found in the equation at the front of the function as a multiplication factor. Here it is 5.

Period is found by dividing the multiplication factor in the function by 2π. So the period is
`(5)/(2\pi )`.
