Our free calculator, ClassCalc, can be used for the 2020 AP take-home exams🤯🤯🤯

An admirable move by College Board to make things as accessible as possible during the pandemic.

On saving his sister from a vicious dog attach: "If someone had to die, I thought it should be me."

That's the face of a proud, courageous older brother.

Everyone ready for Sunday Punday??

A mathematician walks into a bar and say "I'll order 10 times what everyone else is having!"

The bartender says "Wow, that's an order of magnitude"

😂 🤣 😂 🤣 😂 🤣

[Dan Haiem @classcalcdan]

Love the art here. What do you see?

[Dan Haiem @classcalcdan]

Many of you asked about integrating ClassCalc's graphing calculator into proctoring software like Proctorio, HonorLock & Canvas for #distancelearning. We wrote a neat article that will show you how to do just that - FREE!

Fascinating. Words are truly music. You have knobs and gears and if you tweak them to just fit that perfect, changing pace, it'll just sound good. Possibly for no understandable reason.

Anyone have any thoughts on why some patterns just feel and sound good, and some don't?

[Dan Haiem @classcalcdan]

Perspective is everything.

[Dan Haiem @classcalcdan]

@MagisterLudi16 I series what you did there

[Dan Haiem @classcalcdan]

Why did the sound engineer change so much after college?

....

He had a FourYear Transformation. 😂

@STAWBs_Orio Wow so absolutely spot on haha

[Dan Haiem @classcalcdan]

Pick your favorite and tell us why!

[Dan Haiem @classcalcdan]

@DaddyHoggy @standupmaths @3blue1brown @Mathologer Awesome, thank you for the suggestions!

[Dan Haiem @classcalcdan]

I love these math animations. Anyone know of a good place to find more?
Check it out - the Area of Cycloid = 3 x Area of Rolling Circle

[Dan Haiem @classcalcdan]

@standupmaths @DaddyHoggy @3blue1brown @Mathologer I knew it looked familiar, but saw none of the pi creatures or 3B1B branding so had to ask. What a king!

Gonna have to look into adding a dashboards-layer of sorts with a clean UI for non-coders to animate with.

[Dan Haiem @classcalcdan]

Oh man, I goofed on this one. Amplitude and volume...🤦‍♂️

[Dan Haiem @classcalcdan]

In case you have trouble remembering the relationship between amplitude and pitch...

Nifty little video on the Covid genetic sequence

Congrats to everyone #graduating in 2020!

[Dan Haiem @classcalcdan]

There's positive thinking even in negative thoughts.

[Dan Haiem @classcalcdan]

@ACurriculumfor Thank you! She deserves so much more than I can give here.

I love my mother. My mother loves wine. For mother's day, I thought I'd use some #statistics thinking to help her finally resolve, once and for all, which wine is the best wine.
