Hey, I thought this looked familiar! It's the missing pages from a series of "MPotW: traditional vs. IMP trigonometry" posts you did in 2012. You should link these all together, or at least add a "trigonometry" tag to them. I enjoy looking at these, in more than just a schadenfreude kind of way.

For the other listeners in the audience, here are the links to the other pages that I could find:

IHSMMP pp. 4-5 vs. SCA pp. 393-394 (May 18, 2012)

IHSMMP pp. 6-7 vs. SCA pp. 395-396 (January 3, 2014)

IHSMMP pp. 8-9 vs. SCA pp. 397-398 (June 1, 2012)

IHSMMP pp. 10-11 vs. SCA pp. 399-400 (June 7, 2012)

IHSMMP pp. 12-14 vs. SCA pp. 401-402 (today's post)

IHSMMP pp. 15-16 vs. SCA pp. 403-404 (June 21, 2012)

IHSMMP pp. 17-18 vs. SCA pp. 405-406 (June 29, 2012)

IHSMMP pp. 19-20 vs. SCA pp. 407-408 (July 5, 2012)

Thanks GoogleMaster! Yes, I did recycle this one from earlier, as I sometimes do when pressed for time. Thanks for providing all these links. Eventually I will get around to adding a trig tag--good idea!
