2.2 Design an interest factor calculator using EES that will allow you to compute the interest factors shown in Table 2.2. Use the EES Diagram Window to input the annual nominal interest rate, compounding periods per year, and number of years. Return the calculated interest factors in the Diagram Window. Use the calculator to determine the interest factors shown in Table 2.2 for a nominal interest rate of 8% compounded monthly for a period of 20 years.
