On February 2, 2016, an investor held some Province of Ontario stripped coupons in a self-administered RRSP at ScotiaMcLeod, an investment dealer. Each coupon represented a promise to pay $100 at the maturity date on February 2, 2022, but the investor would receive nothing until then. The value of the coupon showed as $76.29 on the investor's screen. This means that the investor was giving up $76.29 on February 2, 2016, in exchange for $100 to be received just less than six years later. a. Based upon the $76.29 price, what rate was the yield on the Province of Ontario bond? (Do not round intermediate calculations and round your final answer to 2 decimal places.) Rate of return % b. Suppose that on February 2, 2017, the security's price was $86.00. If an investor had purchased it for $76.29 a year earlier and sold it on this day, what annual rate of return would she have earned? (Do not round intermediate calculations and round your final answer to 2 decimal places.) Annual rate of return % c. If an investor had purchased the security at the market price of $86.00 on February 2, 2017, and held it until it matured, what annual rate of return would she have earned? (Do not round intermediate calculations and round your final answer to 2 decimal places.) Annual rate of return %

MAT2409 - FOUNDATION MATHEMATICS PAGE 3 OF 4 EXAMINATION PERIOD - SEMESTER 1, 2017 QUESTION 5 (27 marks) (a) The graph of the non-linear function $f(x) = e^{cos(x)} - 1$ is shown in Figure 1. $f(x)$ has two zeros in the interval $0 \le x \le 2\pi$. That is it intersects the x-axis twice in this interval. 1.5 1 0.5 0 -0.5 -1 0 1 2 3 4 5 6 $x$ $-f(x) = e^{cos(x)} - 1$ $-k(x) = e^{\frac{11-\pi}{4}+x} - 1$ Figure 1: Illustration of the functions $f(x)$ and $k(x)$. Consider the following section of code which implements Newton's Method for $f(x) = 0$. xstart = 1; nmax = 100; xold = xstart; count = 1; dif = 0; tol = 1e-7; while ((dif > tol & count < nmax) | count == 1) fx = [exp(cos(xold)) - 1; -sin(xold).*exp(cos(xold))]; xnew = xold - fx(1,:)./fx(2,:); dif = max(abs(xold - xnew)); xold = xnew; count = count + 1; end xfinal = xold; 5 marks 5 marks (i) Line 7 contains the stopping criteria for this iteration scheme. Explain this condition in detail. Discuss what other stopping conditions could be used. (ii) Explain what impact changing line 1 to read: xstart = [1, 5] would have on the calculations.
