    The solution for Forced Harmonic motion is given by: \[Q = Q_{1}e^{\left( -(R/2L)+\sqrt{(R/2L)^{2} - \omega_{o}^{2}} \right)t} + Q_{2}e^{\left( -(R/2L) - \sqrt{(R/2L)^{2}-\omega_{o}^{2}} \right)t} \] If \(Q = A \cos \theta \) and \(\frac{ dQ }{ dt } \approx -\omega A \sin \theta t\) at t =0, also known that \(R/L \approx 0 \) and \(\theta \approx \pi/2\) Find the value of Q1 and Q2! Hbu???

    yess its correct and to draw graph you can either draw on graph paper with neumerical value or you can use logarithmic graph paper
