Talk:2070: Trig Identities

I am confused by the insect line. This seems to be true only if s=t. 141.101.96.209 19:03, 9 November 2018 (UTC)

I added a note regarding how similar it sounds to 'sinsec'. 172.68.51.154 01:47, 10 November 2018 (UTC)

That one and the `cas` aren't making any sense to me. GreatBigDot (talk) 20:02, 9 November 2018 (UTC)

Oh, the casinus is much important to... What was it? --Dgbrt (talk) 20:15, 9 November 2018 (UTC)

cas is realtively easy... it is cos(theta)=a/c -> cs(theta)=ao/c -> cas(theta)=o/c; when you realise that the top one isn't zero but o it clicks 141.101.96.209 23:35, 9 November 2018 (UTC)

You made the same error Randall did: you divided by 'o' on the left and multiplied on the right. I think the theme of the page is expanding significantly upon common math errors that were already humorous, like the common proof of 5=3 by dividing and multiplying by zero. The error here is in line with the theme of casual beginner errors. 172.68.51.154

I think insect is.. a bug.. ;) Smerriman (talk) 20:18, 9 November 2018 (UTC)

Is Enchant at target a magic:the gathering reference? AncientSwordRage (talk) 20:55, 9 November 2018 (UTC)

I think it is a Magic: The Gathering reference. Although it is phrased oddly. You'd think it would be "at target enchantment", rather than "target at enchantment". --Dryhamm (talk) 21:04, 9 November 2018 (UTC)

Voila - s=t.

That was incredible! (assuming previous poster discovered the extrapolated proof in the description) 172.68.51.154 01:47, 10 November 2018 (UTC)

Combining $\cos\theta=\frac{a}{c}$ and $\mathrm{cas}\ \theta=\frac{o}{c}$ allows you to conclude $a^2 = o^2$, not $a=o$.

Somebody added a comment on puns, e.g. that "cin sucks". More explanation is needed. It looks like some kind of a meta-joke. If you ask why, and start interpreting, you see that "b/c" == "because". It might be the answer to why the puns line should be removed, though. 172.68.51.154
