Find the ratio of Beta to Omega(not) for an underdamped oscillator whose amplitude decreases to 10% of its initial value after 4 periods. Explain each step.

For an underdamped oscillator Beta < Omega(not)

x(t) = e^-(beta*t)[Ae^(i(w1)*t) + Be^-(i(w1)*t)]

where "w1" = Root([Omega(not)^2] - Beta^2)

Week 2 HW: Elasticity Step 1 - E L A S T I C or INELASTIC? Price Elasticity of Demand is a measure of how responsive demand is to a change in price. If a price change leads to a considerably bigger change in quantity demanded, we would consider the good to be responsive to a price change—hence elastic. If, however, a similar price change leads to a much smaller change in demand, we would consider it inelastic. To get...
