Integration by Parts, Integral of x*cos(5x)

[@adrieloz50]

Its very easy to understand the way you teach it, thank you very much my friend.

[@CV-br1eu]

Yo thank you, I needed a refresher for my graduate course in heat conduction. Your video explained the basics that i was looking to refresh and also the more intricate parts that a new learner would need. I was able to gather what I needed by 3 mins in and I thank you for this awesome video my brother.

[@blackpenredpen]

Glad to help! 😃

[@DanielGonzalez-vm6rr]

Thank you!!! I undestood more this type of exercices in English with you than in Spanish with my teacher. I really appreciate it.

[@nielpatel6572]

you are the best, you saved me.

[@Nextgenengenharia3d]

Great job! I finally understand the process, it's so simple, nice explication dear blackpenredpen

[@juliestaylor]

Thank you so much! You explain things perfectly, and I really appreciate how you go through every step!

[@koenwilliams2597]

Appreciate u bro thank you so much for this simple explanation

[@denisedigiovanni615]

I love you, it's almost 1 am right now and I'm still trying to solve my excercises. I watched so many videos, but every shwoed some other way. some other cases that made everything pretty complicated in the kind of integral I have to solve. Fortunately thanks to you and your explaination now I have a bit more hope of going to sleep

[@diego03c84]

Thanks! Man your explanation is short and clear🙏🙏

[@daissybee]

Thank you so much! I kept making the same mistake & could not figure out what I was doing wrong. Now I understand.

[@aracely2025]

Now this makes sense. Good work!

[@johnx140]

Brooo,your english is pretty good! And thanks for the explanation.

[@Withheart71]

thank you for doing these. Saving my math career. lol

[@mysteriousmist7335]

Watching your videos before going to sleep is the best way to learn Integration by doing nothing hehe

[@johnzoilob.tolentino6440]

damn thank you. Been having trouble with this problem because I couldnt see any similar problems

[@alfonsocruz7261]

I´d like to share , when we have an IBP, and we don´t know how to find the "u" and "dv" we can use this term "ILATE"
I = An inverse fuction,
L= Logarithmic function
A = Algebraic function
T = trigonometric function
E = exponential fuction
Then, we have already our "u" in this example is X for A= Algebraic function and the rest is cos(5x)dx

Oh My God. This is so useful for me, thanks btw.

[@adriarturo09]

Good work man!! Thank for the explanation.

[@AmanGupta-ti3kf]

you're awesome thank you!

[@leon1297survivors]

so helpfull to my test thank you :)!

[@sarimkhan8622]

sir in integration drivative is divide bt why are u comng it first in integration why are u uze darivative rule?

[@umeshb8210]

osum bro!!
just stopped smashing my head :)

[@blackpenredpen]

umesh Gain what's osum?

[@umeshb8210]

i mean awesome ( extremely impressive)
;)

[@blackpenredpen]

umesh Gain oh thank you! Cool!

[@andrewjsusanto]

Very nice, sir

[@ShowUsTruth]

excuse me where is the du (1) becouse when yo integrate (1) it will be equal to (x)

[@alvaromendoza3337]

Awesome, thanks.

[@celestevalenzuela2714]

A sus órdenes guapo.
Pd: no entiendo ni vrg por qué es inglés 😭

[@andreteixeiradossantos9767]

Thanks my friends!!!

[@wardnproject4599]

Thanks 👍

[@valeriamatti2728]

love you❤
thanks !!!!!!!

[@blackpenredpen]

Valeria Matti you're welcome. Love you too!

[@THEGIANTCOWK]

Using tabular integration is easier

[@farrieshazieqbinnorfauzy4492]

Thank you bro

[@kaathuaami]

Thank you sir

[@muse7504]

cos= -sin right?

[@antoniobastanza8426]

yes

[@swordsy91]

thank you!

[@吴-s5h]

Hi... v= -5sin5x no?

[@MetalTilldeth1]

just perfect

[@blackpenredpen]

thank you thank you~

[@lazarduke6596]

This is so dry. Everything that is shown you have to remember later, ITS NOT WORTH IT!
If you explained why ∫udv = uv - ∫vdu, that would be something

[@nabamaanalhamdani8818]

I can't understand you why
Your way in explain so long ?
