Tables of Fourier series properties as well as CT Fourier transform and dt Fourier transform properties and tables are supplied to you at the end of this booklet. Enter all your work and your answers directly in the spaces provided on the printed pages of this book- let. Please make sure your name is on all sheets. You may use bluebooks for scratch work, but we will not grade them at all. all sketches must be adequately

Fouriers derivation of the ct fourier transform x(t)-an aperiodic signal view it as the limit of a periodic signal as t→∞ For a periodic signal the harmonic components are spaced Oo=2π/ T apart. AsT→∞,Obo→>0, and harmonic components are space

Culture is thought to be the thing only humans have. Studies of animals however, show that chimpanzees can make and use tools like man. Monkeys can learn to do something from each other. Apes can even be taught some forms of language. We find that certain animals do culture similar to that of human beings and the line dividing us from them is not as clear as we used to think

Market orders are to be executed as soon as possible after reaching the exchange floor. Limit orders must specify a price and a time limit, e.g. \Buy 500 at $90, good till canceled.\ A stop order differs from a limit order in that the order is only executed if the specified price, called the stop price, is touched. Stop orders become market orders when the stop price is reached

Chapter 6 presents the supply side of the market using an approach parallel to that of the demand side of the market in Chapter 5. The chapter presents the material in a way that illustrates the second core principle of the textbook, that marginal benefits should equal marginal costs Chapter 5 presents the demand curve as derived from marginal benefit and Chapter 6 presents the supply curve as derived from marginal costs

1. The principle of increasing opportunity cost, also known as the low-hanging-fruit principle, says that the least costly options should be exploited first, with more costly options taken up only after the least costly ones have been exhausted. At low prices, only those with low opportunity costs of producing the product would find it worthwhile to offer it for sale. As prices
