Thank you @DrXyzzy got it :D

Cool, I see assignment-bank pull request in right status bar. Progress is slow with symbolic computing transcription, but I think I'm learning.

Hi, everyone --- the GW course has a class meeting tonight at 6:10–8:45 PM EDT and I plan to have this chatroom open during class for live Q&A. You are welcome to join us.

Hi, I have a little question about the third question of module 1 (Array trigonometry), according to my calculations the answer is:

In [23]: p
Out[23]: 7

In [24]: r
Out[24]: array([ 11.2, 4.7, 6.6])

In [25]: numpy.power((numpy.sin(p/r)),3)
Out[25]: array([ 0.20030151, 0.99009101, 0.66454238])

ans: 0.9900
Is there something wrong? Because I can't check the answer. Thanks in advance...

@IanHawke
@lfgmarcantoni You'll want to round to 4dp, not truncate to 4dp, in order to match the solution.

Use  before and after expression.

Nice!!

@labarba
@DrXyzzy I'm about to announce the "Assignment Bank" broadly and invite contributions. Yours is the first pull request, but it looks like you need to finish it. Go on now!
Hal Snyder
@DrXyzzy
Thanks. There is a second pull request that has been pending for 15 days. It's not finished either, but uses symbolic derivatives instead of infitesimals.
Hal Snyder
@DrXyzzy
numerical-mooc/assignment-bank#2 still pending
Lorena A. Barba
@labarba
We are just looking at the Assignment Bank pull requests now, in fact!
Sigurd Angenent
@SigurdAngenent
Thanks for adding the style files! I added the license, but am getting a little confused with github. I did git commit/git push from my computer. Do I now still have to add a pull request for the updated files on numerical-mooc, or does this happen automatically?
Lorena A. Barba
@labarba
No, when you push your commit, it gets added to the same, open pull request.
Lorena A. Barba
@labarba
Ah wait. Did you add a new notebook in the same pull request? Normally, you should one one pull request for "each thing," with small commits being added to improve the "same thing" in view of the ongoing discussion. Geddit?
Also, it looks like your Cartesian phugoid notebook still has errors? Maybe you just need to rerun it locally and push it with new output?
Sigurd Angenent
@SigurdAngenent
Goddit. I actually thought I had moved the other leapfrog notebook to its own folder, but git is still confusing me. I just updated the phugoid-variation and moved the leapfrog to a separate folder
Lorena A. Barba
@labarba
HI @SigurdAngenent -- what you've done still added the leapfrog notebook to the open pull request.
Gil Forsyth
@gforsyth
@SigurdAngenent , git tracks files, not folders -- so moving the file won't remove it from the pull request
Lorena A. Barba
@labarba
I realize this is confusing. But let's try to sort our way out ... we could merge your pull request, then delete the logistics notebook ... then you make a change to it (otherwise git doesn't recognize anything as changed) and submit a new pull request for the logistics assignment?
Also, it's a good idea to enter commentary directly on the pull request, as we discuss the contribution before merging it ... make sense?
Sigurd Angenent
@SigurdAngenent
I think I managed to remove the leap frog notebook, and it looks like gforsyth just closed the request.
I put the leapfrog notebook in a separate directory and submitted a pull request.

Can't wait the last module : Tsunami: Shallow-water equation with finite volume method and GPU computing. I have always dream of resolve this.

Hello everyone, I had signed for the self paced course but now I've seen the news about a new synchronous run of the course. How do I get into it?
Amit
@amitverma12
Joao Aguirre
@aguirreeng
@amitverma12, thank you. I've done that already. Is there any complete schedule of classes and activities on the course page?
Amit
@amitverma12
@aguirreeng - Progress tab within the course might give you some idea.
Joao Aguirre
@aguirreeng
@amitverma12 Thank you again. I've checked that, I was actually worried if I have already lost some deadline, but it doesn't seem to be the case. Thank you one more time.
Amit
@amitverma12
@aguirreeng - welcome!
Lorena A. Barba
@labarba
@aguirreeng There are no deadlines—in a way, the course is still self-paced, in the sense that the assignments don't have a hard deadline. But the students taking the class for credit may have local deadlines, so you could see that forum posts follow a certain order through the course progression.

Hi Everyone... I am coming from FreeCodeCamp's Gitter DataScience ChatRoom! I hope to know more about this tool! We are doing some research with FreeCodeCamp data there too... Have a look to see what it is going on and please feel welcome to participate and contribute! I prepare a Weekly Digest of the activity in that room so you don't have to see all threads..
Hello everyone, I joined the course today. Feeling enthusiastic about it!
Gil Forsyth
@gforsyth
Hey @mghadam -- welcome aboard! Feel free to ask any questions here or on the openedx forum. The forum supports math typesetting, so that can often be a better place for math-related issues. If you do post in the forum, ping us here, since the forum does not provide notifications for new posts.
Seraphina Anderson
@Seraph2000
Hello everyone! Looking forward to exploring numerical methods with python!
Gil Forsyth
@gforsyth
Welcome @Seraph2000 ! Enjoy the exploration. Definitely ping us in here if you have any questions!

in module 1 of phugoid motion i didnt understand the part where the value of C lies between 0 and 2/3. how is that coming from eqn 15 and 16. can u please explain?
Gil Forsyth
@gforsyth
Hey @arpand1989 -- I responded to your post on the forum (since it supports math typesetting): http://openedx.seas.gwu.edu/courses/GW/MAE6286/2014_fall/discussion/forum/8f31f460c2014a459780160ead626036/threads/572d237bd073487d1c0000b5#

yeah i got it.. thnx :)

@evaristoc
Hi everyone... interested in knowing more about your activities? Can anyone let me know what is the main purpose of this room?
Gil Forsyth
@gforsyth
Hey @evaristoc, it's one of several ways to get in touch with the course creators/maintainers to ask questions
There's a forum on our openedx platform at openedx.seas.gwu.edu that supports math typesetting but doesn't send notifications, so sometimes it's easier to get our attention here
And the course itself is an introduction to numerical methods for discretizing and solving partial differential equations using Python
evaristoc
@evaristoc
@gforsyth Thanks for your quick answer! I didn't know about numeric-mooc. Found it listed in Gitter for people with interest in DataScience topics. It seems that the project is of free access ( :+1: !!). I hope you won't mind if I explore it? I just quickly registered in order to go through the content and decide whether it suits my personal interest and resources. Please let me know in case that was inappropriate?
Sounds an exciting revision/new topic MOOC by the way...
Gil Forsyth
@gforsyth
Hey @evaristoc -- yep, it's all free and open. The github repo has a series of modules, each consisting of a pile of jupyter notebooks and the idea is that you can learn Python and numerical methods in tandem. The course has no end-date, we just keep it running. We do also teach a "traditional" course in the Fall and that's often when we add new material to the course. Definitely explore and use it! That's what it's for! If you have any questions or problems, let us know. Do ping us here if you post on the forums so we know to come and answer.

I am reading the material but I am quiet confused with those equations , and all those things are too much to digest.
