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.

My professor made everything confusing. And when I watched it, I suddenly remember what I learned from Trig

[@ivanlo7195]

so khan academy can make a tutorial about how to have beautiful writing with mouse only

[@TheOtherOne7isBlueMaid]

lol it’s a drawing tablet

[@youngster1943]

It's a electronic oen

[@shashwatsen7150]

CZcams 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.

[@pspmaster2071]

Alexandrewvice I don't think that would work out so well. and it's unnecessary

[@parkercampellone8276]

I mean it already is very profitable for google and very helpful for students lol

[@TheCaptain14]

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.

[@isaiahcampbell3992]

I really like your writing.

[@asim-gandu-phenchod]

Thanks for awesome content

[@otherside9685]

What is that pointer dude, are you aiming

[@ankitaaarya]

Hahaya

[@yerimirey]

how do I make a table of values when the limit approaches π??

[@hikaruu77]

can you solve where my limit is approaching

[@nielsdaemen]

4:30 I learned that the limit is +∞

[@Eli-R]

in the unit circle it's (0,1)

[@polkol8502]

It's graphic is going to near of Y (infinity), but it won't touch the Y in the end of the this approach

[@asd-wd5bj]

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

[@nielsdaemen]

Correct, and all these years later the math makes more sense

[@khandkertiashazad6858]

I think the previous pointer was fine, this one seems a little too big.
.

[@anaykumaroff]

IKR The hell is this?

[@jerge5484]

Nice crosshair

[@LilPozzer]

easy to see that you are sniper

[@midnightsilverpuppy]

How do you know if / when a point is in a specific domain?

[@midnightsilverpuppy]

*keeps watching
"Oh"
Nevermind. Thanks for making these videos and making them available around the world for free. They're great

[@RMAnimations]

i dislike that pointer, it reminds me of a reticle. It's also very distracting.

[@sujithatesh2471]

it is looking wierd(pointer)

[@fareedadahnsiah-eo4is]

Please why's cosine rule using r/4

[@saketgurjar6158]

👍🏻

[@Zaphchial_Mejia]

First-person maths

[@sahilbharodiya217]

plz upload iit question plz sir

[@prat4055]

sunny bharodia dude there's no IIT in USA. He's only gonna post universal questions which can work internationally

[@marksanfelipe3903]

is this guy samuel jackson?

[@miki3386]

00:35 " all trig functions are continuous over their entire domain " what about f(×)=tan(×)

[@JellyfishManiac]

yes. the asymptotes are not part the domain for the tangent function

[@Loverboy1213-c8c]

i don't really get some of the answers..... cos(pi^4) is 0.999... why are you saying it's 0.707....

[@pooplol1]

why does he have a csgo cursor lol

[@noodles450]

I CANT UNDERSTAND ANYTHING

[@wonderfulsleepchan5233]

The black background makes me headache😅
