Problem 2.3 The solution for damped simple harmonic motion is given by \[ x=\mathrm{e}^{-n / 2 m}\left(C_{1} \mathrm{e}^{\mathrm{i}^{\prime t} t}+C_{2} \mathrm{e}^{-\mathrm{i} \omega^{\prime} t}\right) \] If $ x=A \cos \phi $ at $ t=0 $, find the values of $ C_{1} $ and $ C_{2} $ to show that $ \dot{x} \approx-\omega^{\prime} A \sin \phi $ at $ t=0 $ only if $ r / m $ is very small or $ \phi \approx \pi / 2 $.

Use the fraction and exponent templates from the math palette (or use the associated keyboard shortcuts) to enter $\frac{x^2}{3}$ into the answer box. Enter $\frac{x^2}{3}$ here. $\frac{x \cdot x}{3}$ Careful! Be sure the exponent 2 is right next to the x inside the fraction. If the exponent is outside the fraction, your answer may look similar but will be evaluated differently. You will know your cursor is inside the fraction when the blue box for the fraction template displays. You can tell the exponent is inside the fraction when the fraction bar is extended to display beneath the 2, like in the fraction shown above.
