... Find the frequency at which the greatest value of v max occurs. Note: You first have to take the derivative of x(t) with respect to t to find v(t) and thus v max, then take the derivative of v max with respect to ω, which is messy. I suggest that you use Maple to do the derivative with respect to ω. ...
