Absolute max and min values Problem 1 (Multivariable Calculus)
This problem goes over how to find the absolute maximum and absolute minimum values of a function of two variables on a closed, bounded region. It's very similar to how this is done in calculus 1, where you check the values of the function at the critical points and endpoints of the interval. Now, the boundary of a region is a curve.

Peculiar Property of Definite Integrals Problem 2 (The Art of Integration)
Переглядів 3 тис.2 роки тому
Now that we know about Weierstrass substitution we can come back to another integral that we can evaluate with the peculiar property/ The King Rule. This problem is short because we have access to some powerful techniques. After a little bit of algebraic simplification we reduce our integral to one that we previously evaluated using Weierstrass substitution, which is linked below. A Peculiar Pr...
Weierstrass Substitution Problem 1 (The Art of Integration)
Переглядів 2,6 тис.2 роки тому
This is our first definite integral that we'll solving using Weierstrass substitution. The only new part that we haven't covered so far in The Art of Integration is how to convert the limits, which we go over right in the beginning. All of the other conversions for sin x and dx are the same. With a little bit of algebra for a partial fraction decomposition this integral is then a piece of cake!...

The integral of 1dx is a beast of a problem! Thankfully, Weierstrass substitution makes it trivial. Just kidding: this integral is really simple and you already know the answer, x C. Thankfully, Weierstrass substitution gives us the same result.

Integral of sec x with Weierstrass Substitution (The Art of Integration)
Переглядів 3,9 тис.2 роки тому
The integral of sec x is usually taught by using a non-obvious trick: multiplying and dividing by sec x tan x. Here, we go through an alternate way to solve the integral of sec x by making use of Weierstrass substitution. Make sure that you're comfortable with the conversions for dx, sin x, and cos x in terms of t first, which I have linked below: Weierstrass Substitution - Introduction: ua-cam...

Peculiar Property of Definite Integrals Problem 1 (The Art of Integration)
Переглядів 2,4 тис.3 роки тому
This is a beast of an integral! Good luck trying to find an antiderivative for this function. Fortunately, we now have access to the peculiar property of definite integrals known as the King Rule. Once we apply this property the rest of the work is applying basic properties of logarithms and some trig identities. You'll definitely want to be familiar with the peculiar property, linked below, be...
A Peculiar Property of Definite Integrals // The King Rule (The Art of Integration)
Переглядів 12 тис.3 роки тому
In this video we introduce a peculiar property of definite integrals that's known in some places as the King Rule. On our journey to evaluate difficult integrals we've needed to expand our mathematical toolbox to be able to increase our creative problem solving skills. We've used algebraic tricks, creative substitutions, and advanced results like Euler's formula and the gamma function. We're no...
Chain Rule Multiple Times Problem 3 (Calculus 1)
Переглядів 1,3 тис.3 роки тому
This is another really good problem: it involves the Chain Rule being applied multiple times and trig functions. We point out the common error here, which is misinterpreting the inside as tangent being multiplied by sine. By using our shortcuts for the Chain Rule, linked below, the work isn't that bad as long as you remember the trig derivatives. Shortcuts for the Chain Rule - General Power Rul...
Chain Rule Multiple Times Problem 2 (Calculus 1)
Переглядів 1,9 тис.3 роки тому
This is a really good problem on applying the Chain Rule multiple times. We start by making sure that you understand the power notation for trig functions. Once we see this we can identify the outer and inner functions and apply the Chain Rule the first time by using the shortcut that I call the General Power Rule. We then apply the Chain Rule again to find the derivative of cos(3x). This is a ...
Chain Rule Multiple Times Problem 1 (Calculus 1)
Переглядів 3,2 тис.3 роки тому
Finding the derivative of this function requires applying the Chain Rule multiple times. Notice that since we have e raised to a function we need to apply the Chain Rule (we can use the General Exponential Rule). Also, the inner function sin(2x) is a composite so we'll need to apply the Chain Rule again! The work isn't difficult but it's easy to get lost when applying several derivative rules t...
Integral with the Exponential and Floor Functions (The Art of Integration)
Переглядів 1,3 тис.3 роки тому
This is a spicy integral involving the floor function, the greatest integer less than or equal to x. At first glance this integral might seem difficult but there's a nice property that we can make use of: the floor function is constant over integer intervals [n, n 1]. From here we split the integral up into a sum of integrals over integer intervals and use some standard results from calculus 2....

Thanks 👍
The rule is so weird and confusing yet he explained it in the most easiest and understandable way. Thank you, sir!
Thanks
You’re welcome, fellow mathematician
Thankssss😊
You’re welcome, fellow mathematician
Thank you SOOOOO MUCHHHHHHHH!!!!!!!!!!!!
You’re welcome, fellow mathematician!
but when you integrate the fractional derivative of X, you get the wrong result. So you need fractional integrals as well
amazing video thank you
You’re welcome, fellow mathematician
Out of all the videos, this one helped me the most. Thanks!! I hope you come back to UA-cam and continue uploading.
This is such a clear and well explained video, thank you so much!
thanks james
Who’s james?
@@BlackTshirtMathProfessor you kindof look like James McAvoy
Oh. I never got that before. I’ve gotten Justin Timberlake many times but never James McAvoy
Please start making more videos. They are really well done and you passion for the subject is evident!
you are amazing,idk how that video doesnt have too many like but id like to tell you that you are helping lots of students ,keep the amazing work
Good job thank you very much
I appreciate you using the u1 and u2 equations for variation of parameters instead of deriving and doing systems of equations. I have been looking for this. Also nice to combine two different topics to speed up my studies for finals. Good video!
Where are you going it's been two years since u are not uploading sirr😢😢.Please do ur live vlog as a teacher since I want to be a lecture when I grownup.
May god bless you.
❤
It was -8 and +3, but you changed it when putting it in the equation. Why? Is it allowed because you want to cancel out?
i fucks with this heavy
So what does the value of e have to do with e^-infinity^2
7:40 is there a typo ?
Your channel is just right in time before my calculus class. Thank you so much!
Good sir I will kiss you on the lips, thank you for your service
LMAO
4:15 wow this is exactly what i needed to hear lol
goat
🐐
Best explanation on UA-cam sir.
this is the best video i have seen about the gamma function thank you so much! they always skip the integrals :( i always see this is my math book and i always got scaried but now i see that's not that complicated at all
Very nice problem and very clear presentation!
You are very good teacher ... Handsome too .
can you explain how did you get the 8 and -3?
To factor the denominator, find two numbers that multiply to -21 and add to 5: 8 and -3 work.
THANKK YOU, Finally a professor that thoroughly explains the topic and doesnt skips steps and lays it out neatly 💪
His channel needs more subs and exposure bc he explains the topics very clearly
You’re welcome, fellow mathematician!
@@BlackTshirtMathProfessor Haha thank you, I was literally stuck on a Dif Eq problem but this video cleared the way, thank you 🙏
you are good, thanks Black shirt professor. A professor with the cool name
Is it also the answer be y’ = 3(1 + tan(sin x))^3 times sec x squared times sin x times cos x? I mean if it’s okay to include the sec x squared not just sec (sin x)
Beauty video - thanks for helping me understand
THANK YOU! This really helped me for some of my derivative questions regarding product, quotient and chain rule, especially where you had to factor at the end!
Very good and clear explanation, thanks a lot.
Hi sirr , I m just found your youtube channel and your explanation really clear tho with the math working really make me easier to understand❤️
Lifesaver
28:39 The Gaussian integral definitely evaluates to \sqrt{\pi}, however you have half the Gaussian integral since the limits are from 0 to infinity. The answer you wrote down is still correct though due to the 2 out front. Just a minor thing. Great presentation overall!
I am in awe at your ability to create a video explaining layered, complex subjects, all without any editing (save for the simple cut to write out the problem) AND while keeping it extremely digestible. Stellar work - even if you happen to use a script or a teleprompter to help, it's still a rare and hard-earned skill. Major props!
Thank you! I actually didn’t use a script or teleprompter. I just recreated what I do in my courses, which I’ve been teaching for 16 years. I strived to try to create a classroom-like feel by doing it all in one take.
It is really interesting that π appears at so much unexpected places. 😃
Seeing mathematical concepts pop up in unexpected places is one of my favorite things about mathematics!
wow can u make a lot of simplified step by step tutorial for calcuus, this is somehow way more clearer Thanks a lot!
hello! i've recently encountered a problem with both important mclaurin series in one equation, how can i decide which one to use?
Very helpful video, thank you
THANK YOU
THanks very much!! Really helpful!
thank you for this ,what about the ODE of 2rd order do not contain x or y explicitly?
Thnkuu so much sir it's help me alotttt from india thnku so much
Thank you sir
