math for fun, but FAST!

-90° < x < 90° ?

I thought we were all adults now!

3blue1brown would be really proud that you were holding that Pi Microphone in your hands.

Dude, try out some JEE Advance questions, I hope you would find them interesting 😀

If you play it at 0.75x speed, it would looks pretty normal except the sound.

RIP to those who forgot to check convergence of the geometric sequence

[neomosakekana]

Me who watches subbed anime: You call this fast?

[krishnanavati]

you're on a MAT spree! nice stuff! maybe try out some STEP questions? they're much longer but are also more interesting i think.

[davidebarra]

His speaking is so fast I understood only that he is writing something

[shreyan]

Time for putting some ink in that black marker 😊😊

[Danny-lemq]

So does that mean I just got accepted to Oxford...

Please please please
decomposition into simple elements of
* 1/(x^7 -1) in C

How do you know if (1/tanx) / 1 - 1/tanx is equal to tanx? x is an unknown value right?

I love the golden ratio’

[harrymed]

Sir 1 doubt for me in complex numbers..
i²=-1
Now multiply the power with(2/2)
(i²)^2/2
Now ((i²)²)^½
Now (i⁴)^½
We know that i⁴ is 1..so (i⁴)^½ becomes 1^½ = +or- 1
But i²=-1 ...what is the reason for this incompatibility..? Please reply sir..

[akshatjangra]

the golden ratio is seriously everywhere

I think he had planned to record in portrait mode for shorts but by mistake he recorded in landscape mode. So still he had to post it.
