Typo in Section 42 #361

Open rsfairman opened 2 years ago

rsfairman commented 2 years ago

I haven't redone any of the algebra, but on elementary geometric grounds, the formula for control_1 doesn't seem right. It reads:

control_1 = (r,k)

and I think it should read

control_1 = r(1,k)

or 

control_1 = (r,rk)

In fact, as I read further along, it says that

control_1 = (r, 0.55228 * r)

so it's clear that the earlier expression for control_1 is a typo.

thanks for spotting!

You may be interested in why I was looking at your document. I am working on a method to allow composing interactive documents with LaTeX. The body of the text is written in LaTeX, exactly as usual, with the figures in JavaScript so that they can be interactive. The figure could then be adjusted to a particular configuration and saved to a tikz specification, which is then included in the LaTeX document for printing to paper. This way, the paper document and the interactive document are as nearly identical as they can be. I have most of the elements in place, but (like every project), the "last 10%" is 90% of the actual work. This kind of setup might be very well-suited to your Bezier curve document.

...wait, did I never fix this? I'll have to come back to this later today.

This typo is still present, though it doesn't take away from how nicely worded the rest of the document is.
