Hope they get MathJax going here. More fun doing math that looks like math and not COBOL.

Hi all, I'm back now, in case anyone wants to chat.
Hal, we would love to see your symbolic phugoid tutorial … We were going to announce the "Assignment Bank" a bit later, but here you go ...
It's a place for course followers to contribute their own assignments, so ideal for what you did! I recommend that you add a copyright notice somewhere, and ideally license it out under CC-BY for others to use.
Pull request to it.
Hal Snyder
@DrXyzzy
I can post what I have to github. I slowed down when I got to the diff eqs (10) and (11) because I haven't done that in symbolics yet. It's in SageMathCloud, which draws a lot from Maxima and SymPy.
Lorena A. Barba
@labarba
Neat!
Hal Snyder
@DrXyzzy
oops, I just forked assignment-bank. Haven't done pull request before.
Lorena A. Barba
@labarba
That's OK. You can pull-request from there.
Hal Snyder
@DrXyzzy
I can commit a .sagews and a .pdf. How do you want things named? This is a (partial) translation of 01_01_Phugoid_Theory.ipynb
Lorena A. Barba
@labarba
I haven't used SageMathCloud much … can it export to .ipynb? You can name it 01_01_Phugoid_Theory_Sympy.ipynb (or such)
Hal Snyder
@DrXyzzy
SMC can do .ipynb, in fact I have been viewing the first lesson there. But I'm using SMC worksheets to learn that system as well. I'd like to post the sage & SMC versions first, then work back to IPython / Sympy
Ok, need a few min to put things together...
Lorena A. Barba
@labarba
Don't worry, no rush. Just know that our intention was to have the Assignment Bank be a place where everyone can post their variations or extensions on the course.

Hi all. Awaiz from Aurangabad, india
I chose to use git via terminal and when posting my first commit... git comes up with a "Tell me about yourself" error. Learnt the hard way that git was installed but not yet completely configured.
Although the solution can be found easily by running a search, I am writing my adventures none the less.
Lorena A. Barba
@labarba
Did we forget to say how to config git with your name and email on the tutorial?
Awaiz Muakdam
@awaizmukadam
uh I think I might have skipped it the other day..
Let me check once again.
oops
i found my error apologies
Lorena A. Barba
@labarba
I'm actually looking for it and can't find it … where do we say it? (if at all)
Awaiz Muakdam
@awaizmukadam
I was trying to commit using a different email id...
Lorena A. Barba
@labarba
Ah! That'll do it.
Awaiz Muakdam
@awaizmukadam
"Installing git on Linux" has the steps written clearly Lorena..
Lorena A. Barba
@labarba
Ah there it is. I was looking for it in the last unit, playfully titled "Terminal time"
Awaiz Muakdam
@awaizmukadam
In my fault, I had setup GitHub way back during AeroPython... and installed git (local) just last week so I didn't quite supply the right email id during $ git config --global user.email
I was also in "Terminal Time"
might I suggest you add the config part again in "Terminal Time" because the "Tell me about youurself" error won't throw before anyone pushes the changes.. ?
Lorena A. Barba
@labarba
OK, good suggestion. We can add a note and a link back to previous unit.
Awaiz Muakdam
@awaizmukadam
great... thanks Lorena
Hal Snyder

I should probably update README.md too.
Lorena A. Barba
@labarba
OK, we'll have a look!

Phugoid notebook - small issue - the disccusion refers to numbered equations (eg 10, 15) - but none of the equations in the notebook are numbered.
Lorena A. Barba
@labarba
The numbers sometimes don't show up … but they should. We enabled them with some javascript in the notebook style, and some browsers don't show them. Do you not see them when opening on nbviewer or locally?
Chris Short
@ChristopherShort
Perhaps I spoke a little early: loading the notebook's style sheet is in the last cell, and does number the equations - but not completely. Reloading the notebook (or restarting the kernel) does number all equations except the first ones for lift and drag - and so numbering in the discussion appears to be out by 2 (eg what I believe are equations (15) and (16) and labelled (13) and (14) in my local notebook.
Lorena A. Barba
@labarba
Yes, it looks like the equation numbers appear correctly on the nbviewer version, but locally, each time you execute the markdown, it increases the numbers by one.
Chris Short
@ChristopherShort
And looking at the nbviewer version, none of the maths is being rendered at all for me - the mathjax(?) is left raw. I'm on Safari/Mac OX if it matters...but don't think I've seen this as a problem before.
Yes - if you repeatedly run the stylesheet - it increments equation numbers but, for me, fails to label first two equations always.
Lorena A. Barba
@labarba
The fact is, equation numbers are not supported in the IPython Notebook. We decided to hack it with javascript in the style sheet
The other problem of MathJax rendering, yes, it sometimes happens and I don't know why. Cache stuff?
Lorena A. Barba
@labarba
Can you try opening the nbviewer on a new browser window in "private" mode (will not have any history)
FredInChina
@ReblochonMasque
I've always found it was a rather bad idea to "hack" the framework... I'd very much rather work with the plain vanilla notebook rather than see everything break the moment there is a small update. :)
Lorena A. Barba
@labarba
We had a colleague read over the notebooks for friendly review and they insisted on having equation numbers. So we researched and found a way to add them.
FredInChina
@ReblochonMasque
Yes, last sec requirements & changes of scope... I know... LOL
No worries, at some moment it'll work
Lorena A. Barba
@labarba
The issue of MathJax not rendering is something that I can't figure out.
Chris Short
@ChristopherShort
yes - private browsing labelled ALL equations correctly and rendered MathJax! Interesting (in a sad way)
