Fixed copies of Shore 2022 Ext 1 (Q1-12 retyped in Latex to get rid of annotations) and Knox 2022 Ext 1

Expect these + all the selective papers (optimized) for 2unit/Ext 1/Ext 2 on thsc soon (they are uploaded just not indexed yet)

@tywebb I'll add a list of other files that I've optimized and made smaller so you can update your copies.

Thanks for fixing up the Shore paper. Your version looks much cleaner.

Is there a Hunters Hill Ext. 2 for 2022? It is listed at https://thsconline.github.io/s/yr12/Maths/trialpapers_extension2.html but when I try to download it it says 404 Not Found. Also, do you want to put up the Standard 2 papers for 2022 onto the github? There are 8 here: https://www.mediafire.com/file/ozecvpvm8n6yyzp/8-standard-2-trials-2022.zip/file if you want them.

Also in the Shore 2022 Ext 1 LaTeX version Q11c it seems you put the y component for the second vector as m but in the original version it is -1. In the solution it is still -1, not m.

So your version

Screen Shot 2022-09-23 at 12.59.41 pm.png

should be

Screen Shot 2022-09-23 at 12.59.27 pm.png

I also found an error in your LaTaX solution to Sydney Boys Advanced 2022 paper Q11. The original handwritten solution is x=-4 but you put x=4. It should be x=-4.

Also for Q17, in the solution the question was changed to xtanx but it should still be xtan2x.

Now for the Sydney Boys Ext. 1 2022 LaTeX version Q12a you have

There may be other errors in the LaTeX versions but I think they are the main ones.

Thanks @tywebb . I've corrected both SBHS papers and the Shore paper (and have reuploaded it).
Yes there isn't a Hunters Hill X2 from this year so its been removed.

Sorry to bother you again and thanks for the corrections.

But I think you need to look at SBHS Ext 1 2022 again.

You now have for 13ci

But it should be

There is a 2θ at the end, not θ.

And -2sin2kθ should be -sin2kθ ........ no 2 in front.

So in fact they were 3 corrections, not just 1.

Yeah thanks for the pickup I had to correct the line before it as well. It's been fixed now.

The plot thickens.

I can see why you think you may have had to correct the line before ........ but alas you didn't!

The problem was actually in the line before that.

So here is what you have now:

Screen Shot 2022-09-23 at 4.41.33 pm.png
line 3 is correct

This is what you had before:

Screen Shot 2022-09-23 at 4.40.00 pm.png
line 2 is correct

In both cases line 1 is incorrect. cos(2(k+1)θ) should be cos((2k+1)θ) as in the original:

By the way in the sigma notation i-1 should be i=1.

yeah I honestly was reading this paper in a poorly lit room aha. I've fixed it hopefully the last time now.
