Find the resulting amplitude `A'` and the phase of the vibrations `delta`
`S = Acos(omegat) + A/2 cos (omegat + pi/2) + A/2 cos (omega t + pi) + A/8 cos (omegat + (3pi)/(2)) = A' cos (omega t + delta)`

Text Solution

Verified by Experts

The correct Answer is:
`(3sqrt(5))/(8) A, "tan"^(-1)((1)/(5)) `
