Hehehe

I thought this was cute...

#LearningResources #Funny #Teachers

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?"

Calvin Lin Staff - 7 years, 2 months ago

Such a party pooper.

Silas Hundt Staff - 7 years, 2 months ago

learning with fun

U Z - 6 years, 7 months ago

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

Daniel Liu - 7 years, 2 months ago

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

Vishnuram Leonardodavinci - 7 years, 2 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

Raushan Sharma - 5 years, 9 months ago

@Raushan Sharma – Well, the shape looks legit, at the very least. :P I should've also said $0<a<1$ . But of course, you're right in saying that.

Vishnuram Leonardodavinci - 5 years, 9 months ago

Finn Hulse - 7 years, 2 months ago

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

Andrew Tawfeek - 6 years, 1 month ago

Dirac Delta

Michael Mendrin - 6 years, 7 months ago

Hahaha!

Silas Hundt Staff - 6 years, 7 months ago

Dance functions, dance!

Ahmad Naufal Hakim - 7 years, 2 months ago

Wow! Nice drawing!

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

jatin yadav - 7 years, 2 months ago

No idea, maybe @Calvin Lin knows?

Silas Hundt Staff - 7 years, 2 months ago

Chinese for "function dance"

Chung Kevin - 7 years, 2 months ago

@Chung Kevin – @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).

Daniel Hirschberg - 7 years, 2 months ago

@Daniel Hirschberg – Hahaha

Silas Hundt Staff - 7 years, 2 months ago

@Daniel Hirschberg – Lol!!!

Pranjal Jain - 6 years, 7 months ago

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

Julian Poon - 6 years, 1 month ago

@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?"

Trevor B. - 7 years, 2 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

Anqi Li - 7 years, 2 months ago

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

see it see it

U Z - 6 years, 7 months ago

@Suyeon Khim and @Peter Taylor ...

Silas Hundt Staff - 7 years, 2 months ago

Nice, @Silas Hundt

Mardokay Mosazghi - 7 years, 2 months ago

That's funny. :D

Finn Hulse - 7 years, 2 months ago

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

Manoj Kumar - 7 years, 2 months ago

Very funny and cool

Mardokay Mosazghi - 7 years, 2 months ago

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

Shikhar Jaiswal - 7 years, 2 months ago

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

Priyatam Roy - 7 years, 2 months ago

IT'S A VERY GOOD AND FUNNY TOO

VINAY KUMAR AGARWAL - 7 years, 2 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!

Boryana Atanasova - 7 years ago

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

Lavisha Parab - 6 years, 7 months ago

![](url_to_image)

Silas Hundt Staff - 6 years, 7 months ago

Thank you

Lavisha Parab - 6 years, 7 months ago

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

Lavisha Parab - 6 years, 7 months ago

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

A Former Brilliant Member - 6 years, 1 month ago

@A Former Brilliant Member – $\textrm{`text`}$ renders text as output.

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

Prasun Biswas - 6 years, 1 month ago

@Prasun Biswas – Thanks a lot Prasun!

A Former Brilliant Member - 6 years, 1 month ago

@A Former Brilliant Member – Mention not. :)

Prasun Biswas - 6 years, 1 month ago

WOW nice drawing, awesome::)::)

Kutumbaka Jaswanth - 6 years, 1 month ago

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

Kevin Mo - 7 years, 2 months ago

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

Daniel Liu - 7 years, 2 months ago

Ahhh... Thx! @Daniel Liu
