[@mathias_dangi_265]

Are you able to prove that (3w/sin3w)=1, because the only thing I could remember in my calculus class is to prove that (sinx/x)=1. Or do you take a resprocal of it?

[@mya4855]

when you said "make sure your calculator is in radian mode by the way", the world made sense once again.

[@venutiansplane3022]

Me too my friend everything fell into place, there was no past nor future the world aligned and the heavens above blew the horns and twas beautiful and it made sense.... Twas zen.

[@wm396]

How do you do that

[@mya4855]

@@wm396 depends what calculator you have?

[@sevirouskemerut975]

ur comment is a life saver

[@wenwen8237]

can anyone answer me why it should be radian mode btw

[@lillian5353]

I don't think I have ever seen a negative comment on this man's videos. I've never seen someone say "this is a horrible video". I've been using his videos since the 10th grade. I'm now entering university as a first year. I swear by organic chemistry tutor. This man is stronger than thanos himself.

[@erojerisiz1571]

By this point he can just make videos for every known course and we would no longer need school

[@youngscott1074]

No it is his will that make us to study

[@bridramirez6760]

So true! This man has taught me algebra, pre-calc & calculus, general and organic chemistry, and physics. I owe my degree to him

[@iNoodl3s]

I should get college credit for watching his videos lmfao

[@captainrogerdodger144]

This man is magic wow

[@jemilieredito2498]

(sin x) (x) = x sin x (sin x) (sin x) = sin^2 x So it should be limit of sinx/x as x approaches 0 times limit of sin x as x approaches 0. Though the answer is still 0, there’s a problem in the process. Thanks.

[@peorannoane2873]

Thought i was the only one. (^^)

I thought I'd be the first to correct this but here it is

[@FlowinZen]

This correction is for what time in the video?

[@edwardn.8938]

I think I speak for millions of others when I say that you have been the most consistent and high-quality math tutor on this site.

Listen my math prof has been trying to teach this for weeks and when you hit that opening statement and explained it in a way that made sense i nearly came

I'm a first yr. College taking BS Mechanical engineering. I'm a fan of this Guy teaching math and chemistry since I was in Junior High School. One day when I became a Licensed one. I will have some of my savings donated here. So this guy can continue his hobby of teaching.. making every difficult problems become easier to solve.

He's a gem. My real teacher in all my math sequence. I tip my hat for professor Leonard.

[@clarynvanniekerk665]

The fact that I saw at least 3 people in the library watching this man's videos, says a lot!!!!!!!!!!!!

[@tatortrader526]

Thank you so much, I've been following you the last 7 months through my journey of math in pre-cal and now at university. Your videos are the most helpful resource I've found. You're an amazing internet teacher! Thank you for your talent and time!

[@nerijoyceobedoza]

We don't even allowed to use a calculator😭. They required us to solve it manually

[@stefexx7691]

This man blessed me before my limits exams

[@junealeinalgarne6943]

oh my god, thank you so much for mentioning that the calcu should be in radian mode. I've been crying over my wrong answers for weeks, this is my 3rd breakdown this week and I can finally answer my long overdue assignment, thank u so much, may you be blessed for the rest of your life and the next.

[@danstaniigenova4865]

Since I was 9th Grade on my Junior High School, this man always saves me from getting failed scores, now I'm taking my first year in BS Mechanical Engineering, this man still helps me understand my lessons, because I'm having difficulties to cope up when we had online learning.

I'm in my first year of college too, he's saving my semester

You've heard it many times, but you are out here saving lives. I am grateful for your videos.

[@kailieannkimminjinji1855]

The ease at which this man teaches is just uncanny... 👏🔥 kudos to you for explaining this so well!

[@med-tricks5719]

👍

[@husseinalhadi5471]

Excellent video at 13:43 mark shouldn't Sin ^2 = sin (x) X Sin (x) not sin (x) X x

[@agent-if9jb]

agreed.

[@marknzuri9119]

Yeah I thought so too!

[@aliu760]

yeah I saw that mistake

[@benjaminm3180]

Since sin(x) using the unit circle equates to zero, and x is approaching zero (so you plug in zero), either way you write it will be multiplying by zero. I’ll admit I had to pause the video to think about it for a minute to completely understand what he meant but the way he wrote it is still technically viable.

[@silas_mwanikitv]

Yeah! Sure

[@abhishekgamer9576]

Best teacher on the internet i have seen. He don't even introduce himself and teaches excellent.less time and more knowledge .Thank you!

[@1829Emily]

Thank you so much for this video! You’re saving me once again. I always look for your videos when I struggle with math or chemistry

[@rodrj18]

Now thank you so much. Calculus is hard, yet people like you made it easier.

[@evelinortiz7334]

You sir just made everything my professor taught make sense. Doing gods work 👏

[@Calliflower]

You never fail to wake me up from procrastination due to piles and piles of modules to read. Thank you for such elaborate way of teaching us.

[@ninjanigabiyown4253]

The problem where there is sin²x It should be (sinx)(sinx) instead of (sinx)(x).

[@evansraila5519]

It'll still be the same i think...

[@Bbqeee]

​@@evansraila5519 yes bc (sinx/x) will be 1 And as x→0 (sinx) will be 0 So 1*0 will be 0

[@laizat.1300]

Isn't it that sin^2 x = (sin x)(sin x)? Why is it that at around 13:36 of this video, the sin^2 x became (sin x)(x)? Although, the final answer is still gonna be the same. I just got confused. I am hoping for your reply. Thank you. :)

[@m.rizaarrafi411]

i was about to say that, i think he made a little mistake right there

[@guycha0s380]

Yup, it's a mistake

[@bennyteferra7834]

you made this so easy to understand thank u bro

[@ignantxxxninja]

thanks mystery guy.. My College professor tried to explain some of these and complicated it. I appreciate you

[@Daysleaf]

you guys learn these at college ? i'm in 11th grade and we have these stuff

[@ignantxxxninja]

Yup they also have algebra and geometry and some colleges have more basic ones. A lot of technical universities offer calculus but that’s like basic

[@ianruiz6350]

I'm just here scrolling down through comments seeing everybody somehow understanding even though he never explained the why of things. 3:14 how did he know that he had to multiply by 5? 5:39 how did he know he had to multiply top and bottom by 2? 7:33 how did he know he had to do THAT? I just don't see a pattern at all. It feels like he's explaining how to do the specific problems rather than teaching us how to analyze problems on our own. I'm gonna be solving all of these thinking I understand them then when the tests arrives I won't even be able to know where to start or how to tackle the problem.

Trying to find the limits of trigonometric functions are probably one of the most complicated things when entering to the realm of calculus.

why are these better than any teacher i have. wtf is the point of skool in 2019...
