7.18.1.1 How can I draw the trefoil knot in 3D co-ordinates in Latex using these parametric equations?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=587156

When I use the parametric equations (according to Wikipedia) to plot a trefoil knot: 
x(t)=sint+2sin2t 
y(t)=costa^\210\2222cos2t 
z(t)=a^\210\222sin3t 
I get a plot that looks very different from the nice plot on ...

7.18.1.2 Why are my TikZ intersections not exact?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=587371

In a TikZ picture, I try to intersect an arc with a cubic bezier line. However, the calculated intersection points seem off a^\200\224 do you know why that is? Is this some sort of rounding error?

7.18.1.4 How to put a curvearrow around a letter?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=587413

In physics, it's sometimes useful to draw an arrow over a letter to represent the torch around that point. I've seen this in multiple textbooks and would like to know how to do it myself in \LaTeX ...

7.18.1.6 How to center vertically small (tiny) equation numbered tags?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=586933

The following MWE procudes this result: 
As you see, I want to have tiny equation numbers/tags, but currently it is not centered vertically of course (as the rule shows), it lies on the baseline. How ...

7.18.1.7 Dimension Lines in 3D drawings

https://tex.stackexchange.com/landing/r/digest?cta=question&id=587510

I am trying to apply Tikz-dimline label position (Dimension lines) to a 3-dimensional drawing.  This has worked well for me in 2D, so thought it would do so in 3D. 
Thus, when in  a 2D drawing I would ...
