BEEC 1323 Mini-Project TOPIC 4 1. The table below shows price per gram of 3 different material (Gold 977, Silver 699 and Platinum 777) for the pass 15 years. Gold 977 (RM) 120 Silver 699 (RM) 2.5 Platinum 777 (RM) 50 YEAR 2001 2002 2003 2004 2005 129 150 2.7 2.4 49 53 143 151 2.1 3.0 60 65 146 141 mm 3.1 3.5 3.7 4.2 52 61 69 72 139 155 86 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 159 160 3.8 3.2 91 141 155 4.5 4.4 106 118 126 132 167 171 4.1 4.0 a) Plot the price of each material (Gold 977, Silver 699 and Platinum 777) in Matlab. b) Use MATLAB to calculate the average and standard deviation of each material. c) In early 2001, Jamil, Muthu, Ah Seng decided to invest in comodity with each of them have RM16, 800 to invest. Using all of their money Jamil has bought Gold, Muthu has bought Silver and Ah Seng has bought Platinum. Using MATLAB calculate their money if each of them sell 1/14 of their comodity for each year start from 2002 until 2015. Plot a graph and find out who is more profitable. 2. A function v(t) is given as: v(t) = 10e2t sin(500xt) Plot the function v(t) using 10, 25, 50, and 100 points
