Some accurate trigonometry jokes.

by sonone, Jun 20, 2020, 11:07 AM

Here are some trig jokes I came up with:
Joke #1:
(Now, you are doing a "First!", "Second!" marathon in someones blog shout box. If you happen to be second, do this.)
If $o=3^\circ,n=7^\circ,$ and $d=10^\circ$ , then $\sec(ond)$ !
Why it is accurate

More jokes to come! (I will add when one pops to my head, like the first one did

)

$\cos 3^\circ \ne \frac 12$ . I think you meant $\cos 30^\circ$ ?

Wait. This is super late and all, am I'm probably just being dumb right now, but isn't this wrong?

Isn't $\cos 30^{\circ}=0.86\ldots$ and $\cos 210^{\circ}=-0.86\ldots$ ?

I checked on the calculator after I started to doubt myself... :read:

This means it's wrong in two ways:

Both $\cos 30^{\circ}\not =\tfrac{1}{2}$ and $\cos 210^{\circ}\not =\tfrac{1}{2}$ .
Also, $\cos \left(\theta\right)=-\cos \left(\theta+180^{\circ}\right)$ , so $\cos \left(\theta\right)\not =\cos \left(\theta+180^{\circ}\right)$ .

It'd work with $\cos 60^{\circ}=\cos 420^{\circ}$ , however.

Or I'm just not thinking straight. :wacko:

i think i agree with @above

but also, you can't exactly multiple angle values, because then it would have to be $\text{120}^{\circ^3}$ , which is wonky. It would work with something like $o=6$ , $n=5$ , and $d = 10^\circ$ , though.

[REVIVAL] I will start posting more calculator relating posts very soon. Even though school has been busy, I have been programming my calculators a decent amount, so I have a lot to share...

Could you make more Asymptote lessons on your "How to do Asymptote" blog?
by violin21, Aug 9, 2021, 7:26 PM
You can take it, just C&P the CSS into your CSS area
by sonone, Apr 17, 2021, 10:08 PM
how can we take the CSS if we have permission to not take it?
by GoogleNebula, Apr 17, 2021, 5:22 PM
That is awesome!
by sonone, Apr 15, 2021, 10:09 PM
I modified your dodecahedron and got:
[asy]
import three;
import solids;
size(300);
currentprojection=orthographic(0,1.3,1.2);
light(0,5,10);

real phi=(sqrt(6)+1)/3;
real g=(phi-1)/2;
real s=1/2;
real a=sqrt(1-phi*phi/4-g*g)+phi/2;

triple[] d;
d[0]=(phi

Not too many, just changing the color here and there. I really like your CSS!
by sonone, Feb 2, 2021, 10:35 AM
Nice!

I see you're making changes to the CSS.

And I took part of it from CaptainFlint and then added a ton of modifications.

When it says "At least 11 users clicked that button" it's incorrect since one person could have just posted 11 times. It should say "At most 11 users click that button".

I can't get the cursor to work.
by G.G.Otto, Apr 25, 2020, 6:38 PM
If the cursor is confusing, where you are actually pointing in a front of the ship

It's ok $\text{[math]}$

Sorry I haven't been posting. I've got a Research Paper (for Roman History) due in a week.

You should download it, as it's really useful when learning python. You can find out more here

No. I don't have IDLE.
by sonone, Apr 18, 2020, 7:49 PM
Do you have IDLE installed on your computer? If so, I can give you a couple really cool codes that made that don't work in the AoPS widgets.
by G.G.Otto, Apr 14, 2020, 6:47 AM
I don't know how to change it....
by G.G.Otto, Apr 5, 2020, 5:58 PM
Do you know how the change the into thing above my avatar a different color? It's too hard to see.
