For each function, have a comment block at the top with the file name, your name, the exercise number, and the date.  In MATLAB, to copy the interactive session, first open a new file (File => New => Script).  Next, use the mouse the highlight the text, right click and select 'copy'.  Finally, in the new window paste in the text (Edit => Paste).  Save your files in a folder and save the contents to a compressed file hwkx.zip

Homework Problems

1. The area of a triangle is b*h/2 where b and h are the base and height, respectively.  Write a function 'triangle(bh)' where bh is a two dimensional array.  The first and second columns are base and height values, with each row corresponding to a triangle.  The function returns the area of the triangles in a column vector.
   1. Produce your funtion triangle.m
   2. Consider triagles with base and height values given as ordered pairs: (1,2), (2,3), (3,4), (4,5).  Use the function interactively, demonstrating how you used the function interactively.  Copy your results into 'triangle.txt'

2. Ex 6.10 - Part (c) only.  Conider centigrade temperatures 0, 10, 20, and so, ending at 100^oC.  As in the first exercise, demonstrate how you used the function.  Copy your interactive results into 'C_to_F.txt'

3. Ex 6.3 - As in the first exercise, demonstrate how you used the function.  Copy your interactive results into 'future_value.txt'

4. Ex 6.4 As in the first exercise, demonstrate how you used the function.  Copy your interactive results into 'nmoles.txt'
