Comment on T * sin (t)' ≈ Ornamented Christmas Tree (2013)parent

Comments

I checked the post, but it's from someone who's far more comfortable with Mathematica than I am, so I hope you won't mind my asking about the maths.

First, the T vs. t in T * sin(t) doesn't mean anything, right? Second, the ' in the title T * sin(t)' doesn't belong, right?

Then I think that this is graphing essentially (t * sin(t), t * cos(t), t + something), which is a cone if the something is constant, which I believe it is—and that certainly matches the graph. And the rest is about choosing an aesthetically pleasing step size and accomplishing the lovely twinkling and colors, right?

I added the prime in the title to indicate that this version is a bit different from the original t * sin(t) post.

OK, thanks. Is the rest of it right?
