The pro- gram should display how many terms are used in the sum. 8.9 One of the programs in Section 8.2 shows that an amount of $1000 will double in eight years with an interest rate of 10 per cent. Using the same interest rate, run the program with initial balances of $500, $2000 and $10 000 (say) to see how long they all take to double. The results may surprise you. 8.10 Write a program to implement the structure plan of Exercise 3.2. 8.11 Use the Taylor series cos x = 1- +4 + 2! 4! +... 6! to write a program to compute cos x correct to four decimal places (x is in radians). See how many terms are needed to get 4-figure agreement with the MATLAB function cos. Don't make x too large; that could cause rounding error.
