The tabs should be labeled accordingly and should include a presentation of the raw data as shown in each question and of the graphics and information requested.

**Question 3.**

Create a table showing the relationship between D and V for the following values: d = 0.25, n = 2, d_{p }= 0.5, C = 5, and q = 45°, using the relationship shown below. Remember that you must convert to radians when using trigonometric functions in Excel. Also, create an xy plot of this relationship. Make sure to include appropriate titles, labels, etc., and to make everything visually pleasing.
