Question
Find the solution of the initial value problem:
z" +7.84x = 5 cos(3t), (0)= '(0) = 0
r(t) = 116 [cos (√7.84 t) - cos (3r)]
Graph the solution to confirm the phenomenon of Beats. Note that you may have to use a large wind-
one beat.
What is the length of each beat?
Length 1.1652-7.84
Would you be able to explain why the beats phenomenon occurs for this particular example?
