Today we will try to develop test questions.

We need access to Python

 * Available on most campus computers (including our little lab laptops)
 * See also https://www.python.org/downloads/ is you want to download one on your laptop

Next we need to get Python files to improve
Start here: https://bitbucket.org/Guy_vandegrift/qbwiki/wiki/Home
 * From the aforementioned wiki Click Source to get to:
 * Source Look in OSUP-1-5-unfinished to get chapter 5 questions. We begin with problem 33 at:
 * up1-5-33 Use the 3 dots and open raw to get to:
 * a python file you can save

Latex
If you have Windows and are willing to waste a lot of time download Miktex at: https://miktex.org/. But it is far simpler to upload the question only (after deleting the \ifkey footnote):
 * https://latexbase.com seems to work, at least for now.
 * I have no experience with https://www.overleaf.com/user/subscription/plans

W: Mit labs and meeting

2/8 Fri: Learned one wikiquiz

 * Wright_State_University_Lake_Campus/2019-1/Matlab
 * Did both sections do this?
 * Any questions about the test?

Differentials and energy conservation
Note dot product:
 * read
 * don't read
 * $$F_xdx=mv_xdv_x=\tfrac m 2 dv_x^2 = d\left(\tfrac 1 2 mv_x^2\right)$$
 * $$F_ydy=mv_xdy_y=\tfrac m 2 dv_y^2 = d\left(\tfrac 1 2 mv_y^2\right)$$
 * Add these equations together:

$$F_xdx+F_ydy=\tfrac m 2 d\left(v_x^2 + v_y^2\right)$$
 * In vector notation:

$$\vec F\cdot d\vec r=\tfrac m 2 d(\vec v\cdot\vec v) = d\left(\tfrac 1 2 mv^2\right)$$
