Precalculus PF Accessibility #921

I know nothing about how to do this, but just wondering if you are able to change what is said? Like, instead of "minus 2 pi" is there a way to have it say "negative 2 pi"?

[Activity 7.1.10
https://8436599a.tbil.pages.dev/preview/precalculus/PF1#activity-sine-phase-shift-1](url) - part b choice D does not have the accessibility feature (it doesn't talk to me! :))

Not a part of this pull request, but since we are here....

I believe the hint in part d of Activity 7.2.17 [Activity 7.2.17
https://80a10de7.tbil.pages.dev/preview/precalculus/PF2#PF2-3-13](url) should just say the zeros (and not asymptotes)

In [Activity 7.3.5
https://2ee4ecd2.tbil.pages.dev/preview/precalculus/PF3#PF3-3-6](url), answer choice B: although it shows it is supposed to say "negative pi over 2" it doesn't actually say it....and the same is true for choice D.

I am not sure why, but for multiple graphs in section PF3, I am not seeing the full graph within the given domains. Or it doesn't show the entire graph - like I can see the points, but they are not connected (see image). I don't know if it is just my computer but thought I should mention it.

I also see this, I suspect there is a PreTeXt bug and have inquired on the listserv.

I have inquired to see if there is a way to change this systematically. Otherwise, we will have to go through all of the annotations everywhere and change "-2" to "negative 2"

@siwelwerd can you take a second look this file and make it's what you want? When I click on this figure (in Activity 7.3.2), it immediately zooms on the angle theta and won't let me navigate away from it. Possibly an error on my part, but wanted to confirm with you

I added some annotations that are hopefully more useful
