If I understand what you mean, then in a situation where no one ever will want arrows, you can go like \addplot+[-]
and the -
(no arrows) will be applied following the pgfplotscycle parameters and overrule the <->
. I'll almost certainly catch these when I get here.
Yes, exactly. I didn't know that would work. Do you still need the "smooth" when the plot is a set of points? Also, I probably set the sample
parameterizing with respect to arc length to avoid that?

I think you would need smooth
if you are making a curve by declaring coordinates. I did not put that in the default styles because it puts an extra burden on computation.
For plots that look angular because of samples, I try to use polar coordinates or hyperbolic coordinates first. Both systems are still centered at the origin, so maybe also shift. For example, to plot y=sqrt(x+3)
, I'd settle on polar coordinates, centered at (-2,0). So x=r*cos(t)-2
. And solve for r
in the equation r*sin(t)=sqrt(r*cos(t)+3)
to get whatever you get, which I'll call r=f(t)
here. Then I'd work it through without simplifying anything like:
\addplot+[...] ({x}, {sqrt(x+3)});
\addplot+[...] ({r*cos(t)-2}, {sqrt(r*cos(t)-2+3)});
\addplot+[...] ({f(t)*cos(t)-2}, {sqrt(f(t)*cos(t)-2+3)});
Then you can either change the variable to be t in the options or change the t
's back to x
's. And you need to replace t
with deg(t)
inside trig functions.
Would you like me to merge this PR? I can revise any image stuff when I catch up to you. Or you can change things in this PR. Or in another PR. If you want to merge this one, go ahead. I might be away form email a bit today.
Oops. I screwed that up. "Solve for r
in the equation r(sin(t))=sqrt(r*cos(t)-2+3)
."
Go ahead and merge it and catch anything you find on your pass. I'll look at that PR carefully to see what you end up changing. Maybe do the WebWork as a separate branch?
I think I only kept the smooth part where it was coordinates. I agree that we don't need it globally.

I won't make any further edits on this section until you've had a chance to look at it.

OK. Even if I don't do WeBWorK stuff in a different branch, I'll do it on a separate commit for sure. You can view diffs from individual commits within a PR.
Did not fix periods inside math. Also, I left a lot of the implicit functions as sets of points. I think that is best. Alex, I left you some todos in terms of graph styling on a closed curve. Not sure if you want to create a style for these so that the arrow heads don't show but that the colors are consistent with the rest of the graphs.
