Project 4A: Calculate the Area Moment of Inertia of Rectangle, Square and Circle

(http://en.wikipedia.org/wiki/List_of_area_moments_of_inertia) with inputting dimensions. Print “Wrong dimensions” next to the Input

cells if any negative number is entered. Calculate in three different areas within the same worksheet (same tab). See Project 4A

Example.pdf in the unit.

Project 4B: Write an Excel program to convert temperatures from Fahrenheit to Centigrade and vice versa with inputting respective

temperature values that to be converted. The operator should have an option to select what he/she wants to convert to. See Project 4B

Example.pdf in the unit. Conversion formula can be found at http://en.wikipedia.org/wiki/Conversion_of_units_of_temperature.

Project 4C: Draw Sine and Cosine curves for 0<=θ<=360o with angle as x-axis and trigonometric value as y-axis (θ increment should be

15o). See Project 4C Example.pdf in the unit. Graphs are required.

Project 4D: Redo Problem 2A using VLOOKUP function in the last column. Include at least a case for each letter grade, including

“Fail”. You may want to add more students for this requirement. Graphs are not required. However, you can leave them there.
