Show that the partial sum Sn defined by the recursion formula: Sn+1 = 3Sn with S1 = 1, converges to 3. Use mathematical induction. 6. Does the series N n=1 1 n converge as N → ∞? 7. Suppose Xn = aXn + 1 with X0 given. Write Xn as a partial sum. When does this partial sum converge? 8. Consider the function: f (x) = x3 (a) Take the integral and calculate (c) What are the differences between these two sums and how well do they approximate the true value of the integral?

Once a market participant gets some practice, it is easier to work with continuous-time tools than their discretetime equivalents. The mathematics of derivative assets assumes that time passes continuously. As a result, new information is revealed continuously, and decision makers may face instantaneous changes in random news. Hence, technical tools for pricing derivative products require ways of handling random variables over infinitesimal time intervals. The mathematics of such random variables is known as stochastic calculus.

How would you form an arbitrage portfolio? 6. Suppose you are given the following data: • Risk-free yearly interest rate is r = 6%. • The stock price follows: St − St−1 = μSt + σ St εt where the εt is a serially uncorrelated binomial process assuming the following values: εt = +1 with probability p −1 with probability 1 − p The 0 < p < 1 is a parameter. • Volatility is 12% a year. • The stock pays no dividends and the current stock price is 100. Now consider the following questions. (a) Suppose μ is equal to the risk-free interest rate: μ=r and that the St is arbitrage-free.
