This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
• Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Sorry to be a party pooper, but $y = \sin x$, $y = \log_a x$ are wrong.

$y = a^x$ should also include the qualifier $a> 1$ lol.

Perhaps we should make this an MCQ of "How many mistakes are there?"

Such a party pooper.

learning with fun

You're just jealous you don't have those dance skills ;D

- 6 years, 4 months ago

$y = sin x$ is definitely wrong. I reckon $y = \log _{ a }{ x }$ is right if $a < 1$. Maybe I'm wrong. Lol.

- 6 years, 4 months ago

If $a<1$, then also the graph is wrong. The domain of the function is positive real numbers, so the graph is definitely wrong

Well, the shape looks legit, at the very least. :P I should've also said $0. But of course, you're right in saying that.

Ahaha I was actually looking at some of these and thinking to myself some seem a bit off!

Dance functions, dance!

- 6 years, 4 months ago

Wow! Nice drawing!

By the way , what is that written on the top ?

- 6 years, 4 months ago

No idea, maybe @Calvin Lin knows?

Staff - 6 years, 4 months ago

Chinese for "function dance"

- 6 years, 4 months ago

@Silas Hundt I want a video of the Brilliant team doing this dance, set to The Safety Dance. Bonus points for @Calvin Lin stubbornly doing the correct sin(x) and log(x).

- 6 years, 4 months ago

Hahaha

Staff - 6 years, 4 months ago

Lol!!!

- 5 years, 9 months ago

However, converting the words to Chinese (Direct translate) is maths (physical) exercise, with my interpretation.

@Silas Hundt There's a poster of this in my old Precalculus class, with one addition: a person with his arms all tangled up labeled "WTF?"

- 6 years, 4 months ago

This brings back memories... I was forced to do this "dance" during our club session once... And the last one was some tangled arm thing labelled as crap

y = [x] , this function makes it a grand party!

see it

Nice, @Silas Hundt

- 6 years, 4 months ago

That's funny. :D

- 6 years, 4 months ago

Sir now you dance in parties like that's :)

- 6 years, 4 months ago

Very funny and cool

The Last One is missing!!......a strange hand movement and was termed as 'crap'

And poor hyperbole just can't help but glance at their asymptotes :p

IT'S A VERY GOOD AND FUNNY TOO

- 6 years, 4 months ago

That is very good idea to learn functions with my children:) Thank you! We will make them without mistakes. But also I think that it will be good to present them with any mistake, which the children have to find them!

This is irrelevant, but how to attach pictures in notes?

Staff - 5 years, 9 months ago

Thank you

- 5 years, 9 months ago

But will it be shown as this pic or as a link?

- 5 years, 9 months ago

How did you write the format for pasting a pic , with a box around it ?

- 5 years, 2 months ago

$\textrm{text}$ renders text as output.

Those "quote"-like marks are given by the key which is exactly below the "Esc" key.

Thanks a lot Prasun!

- 5 years, 2 months ago

Mention not. :)

- 5 years, 2 months ago

WOW nice drawing, awesome::)::)

- 5 years, 2 months ago

WAIT A MINUTE, I thought Mathfights shared this.... Hmmm, @Daniel Liu . But very cool and very funny :D @Silas Hundt

- 6 years, 4 months ago

No, Mathfights got it from reddit or tumblr or 4chan or another one of those places.

- 6 years, 4 months ago

Ahhh... Thx! @Daniel Liu
