Step 1
Given the differential equation: \[ x'' + 5x' + 100x = 6 \sin(2t), \] we assume a particular solution of the form: \[ x_p(t) = A \cos(2t) + B \sin(2t). \] Show more…

The equation of motion of a body performing damped forced vibrations is $\frac{\mathrm{d}^{2} x}{\mathrm{~d} t^{2}}+5 \frac{\mathrm{d} x}{\mathrm{~d} t}+6 x=\cos t .$ Solve this equation, given that $x=0 \cdot 1$ and $\frac{\mathrm{d} x}{\mathrm{~d} t}=0$ when $t=0 .$ Write the steady-state solution in the form $K \sin (t+a)$ $[$ see 13].

Obtain the general solution of the equation $$ \frac{\mathrm{d}^{2} y}{\mathrm{~d} t^{2}}+4 \frac{\mathrm{d} y}{\mathrm{~d} t}+5 y=6 \sin t $$ and determine the amplitude and frequency of the steady-state function. [ Note: The steady state function describes the behaviour of the solution as $t \rightarrow \infty]$
