Lab 3 pre-submission notes

Hi everyone,

Just a few notes on things that came up during lab on Friday:

a) When referencing the lecture slide #39 for calculations, make sure you're using the "Spring 2012/13" lecture, and not the "Fall 2012/13" lecture, which was posted on Blackboard earlier in the week.

b) Engineering notation in Excel.  Please note the difference between engineering notation and scientific notation - the exponent in engineering notation should be +/- 0, 3, or 6.  In Excel, you can still format your cells to be in engineering notation.  Go to Format Cells, custom, and choose ##0.0E+0 from the menu (or type it in yourself).  Here's an example of how numbers should look in each notation:

Number	Engineering	Scientific
1	1.0E+0	1.00E+00
10	10.0E+0	1.00E+01
100	100.0E+0	1.00E+02
1000	1.0E+3	1.00E+03
10000	10.0E+3	1.00E+04
100000	100.0E+3	1.00E+05
1000000	1.0E+6	1.00E+06
10000000	10.0E+6	1.00E+07
100000000	100.0E+6	1.00E+08
1000000000	1.0E+9	1.00E+09

c) Please note that an Excel file of your graded lab has been uploaded to Blackboard, you'll get this feedback for each lab.

Have a good weekend!
