 Homework Statement:

Determine the deviation at a time when the amplitude has
dropped to 1/5 of the original value.
 Relevant Equations:
 A=A0 e^bt
Hi !
Problem :
y = 5 e^0.25t sin (0.5.t) (m, s). Determine the deviation at a time when the amplitude has
dropped to 1/5 of the original value.
I tried with A=A0 e^bt=5 e^0.25t
 Do i need to determine the time here or recreate the deviation equation when A decreased ? I don't understand the meaning of the question .
