Appreciating that all trigonometric functions are continuous over their domains. Because of that, a limit to a point in a trig function's domain will be the value of the function at that point.

so khan academy can make a tutorial about how to have beautiful writing with mouse only
lol it’s a drawing tablet
It's a electronic oen
Dum
😭😭😭
My professor made everything confusing. And when I watched it, I suddenly remember what I learned from Trig
RUclips is the Best School in the world. Seriously If youtube can just work with the government, This Platform could be very VERY profitable for Google and Very Helpful for students.
Alexandrewvice I don't think that would work out so well. and it's unnecessary
I mean it already is very profitable for google and very helpful for students lol
Sometimes I look at Khan Academy videos in my subscription box and think, "Hasn't Sal covered this topic 7 times already?" I still watch, regardless.
4:30 I learned that the limit is +∞
in the unit circle it's (0,1)
It's graphic is going to near of Y (infinity), but it won't touch the Y in the end of the this approach
It's an ancient comment, but just in case anybody stumbles upon it - one must differentiate between Real Numbers (where ∞ isn't a valid element) and Expanded Real Numbers (Where ∞ *is* a valid element and in certain contexts can be treated as number). In the former, way more common set, division by 0 is undefined, in the later it's precisely +∞. The answer depends on the context
Correct, and all these years later the math makes more sense
What is that pointer dude, are you aiming
Hahaya
Let my dude be 😭
can you solve where my limit is approaching
I think the previous pointer was fine, this one seems a little too big.
.
IKR The hell is this?
I really like your writing.
how do I make a table of values when the limit approaches π??
i dislike that pointer, it reminds me of a reticle. It's also very distracting.
How do you know if / when a point is in a specific domain?
*keeps watching
"Oh"
Nevermind. Thanks for making these videos and making them available around the world for free. They're great
easy to see that you are sniper
Nice crosshair
00:35 " all trig functions are continuous over their entire domain " what about f(×)=tan(×)
yes. the asymptotes are not part the domain for the tangent function
Thanks for awesome content
Please why's cosine rule using r/4
First-person maths
it is looking wierd(pointer)
plz upload iit question plz sir
sunny bharodia dude there's no IIT in USA. He's only gonna post universal questions which can work internationally
i don't really get some of the answers..... cos(pi^4) is 0.999... why are you saying it's 0.707....
why does he have a csgo cursor lol
👍🏻
is this guy samuel jackson?
this tutorial needs a tutorial
I CANT UNDERSTAND ANYTHING
The black background makes me headache😅
