Solve problem 4.2, but with a modification to estimate the solution to six significant figures, from textbook (Chapra \& Canale, 7th edition) For you solution you must show at least calculation examples for the first two iterations as presented in class. Also, you might use MS Excel and provided your files. Feel free to re-use the MS Excel files developed in class which is available in Moodle. The true solution can be calculated using your pocket calculator or MS Excel, remember to set you calculator in radian mode for trigonometrical calculation. You might compute in excel as =pi(). Assigned problem are provides below. 4.2 The Maclaurin series expansion for cosx is cosx=12x2+4!x46!x6+8!x8 Starting with the simplest version, cosx=1, add terms one at a time to estimate cos(/3). After each new term is added, compute the true and approximate percent relative errors. Use your pocket calculator to determine the true value. Add terms until the absolute value of the approximate error estimate falls below an error criterion conforming to Npe significant figures
