MULTISTEP In this problem, you are to use the result of to derive Equation 14-51. At resonance, the denominator of the fraction in brackets in 105(e) is and has its maximum value. For a sharp resonance, the variation in in the numerator in this equation can be neglected. Then, the power input will be half its maximum value at the values of for which the denominator is (a) Show that then satisfies (b) Using the approximation show that (c) Express in terms of (d) Combine the results of Part (b) and Part (c) to show that there are two values of for which the power input is half that at resonance and that they are given by Therefore, which is equivalent to Equation 14-51.
