Chapter Notation #18

Closed Peter230655 closed 2 years ago

Peter230655 commented 2 years ago

Small point: In the notation chapter you mention the outer product of two vectors, the symbol being the ‚circled x‘. I could not find the definition in your script. (I found the definitions of the other products you mentioned there.) I assume that if v, w are column vectors, the outer product is dot( v, w.T).

I have introduced it yet. Just put it in notation too early! I'll bring it up when I get to inertia.

moorepants commented 2 years ago

I'm going to introduce things as we need them, to some degree. Instead of giving all the info upfront.

@Peter230655 would you be interested in formally review the text for me as I go along? If so, I could do a video call with you to show you some of the technical aspects of doing reviews in Github. If interested let me know. I'll certainly add you in the acknowledgements if so.

Dear Jason,

I would certainly be very happy to do so! Whether I am qualified to do it, only time will tell! :-))

Yes, you would have to tell me these technical aspects of Github, I am TOTALLY ignorant of those matters. I would prefer to have my son with me during this zoom call, as chances are, he will understand these details much faster than me. This means, best on a Saturday or Sunday, if this is o.k. for you!

Thanks again, Peter

@jtheinen If it is possible to use SVG's for the handwritten notation, I'd prefer that over a png as I said in when we meeting. You can open the svg files of the existing figures in inkscape, delete everything but the notation you want and then resize the page to the content and save as a new file. I can also make a single svg for you with all the notation handwritten in my style. Maybe that's easiest.

The outer product is now defined in the notation page, closing.
