Question

Find the amplitude, the period in radians, the phase shift in radians and the vertical shift shows solving steps.

Answer 1

`y = Acos(Bx - C) + D`

The A is amplitude, B is to find the period, C is the phase shift and D is the vertical shift

Amplitude =
`A = (1)/(7)`

Period =
`(2\pi)/(B) = (2\pi)/(8) = (\pi)/(4)`

Phase shift =
`C = - (\pi)/(6)`

Vertical shift =
`D = -5`
