1. The problem statement, all variables and given/known data Consider an underdamped harmonic oscillator (Q > 1/2) with a sinusoidal driving force Focos(ωdt). (a) (5 pts) By using differential calculus find ωd that maximizes the displacement amplitude. (b) (7 pts) By using differential calculus find ωd that maximizes the velocity amplitude. 2. Relevant equations x(t)= (fo/m)/sqrt([wo^2-wd^2]^2+(gama(wd)^2) 3. The attempt at a solution I know what the end solution will be and the general theory behind this but I am unsure how to proceed. I am unsure how to prove the point at which it is the maximum.
