i saw so many other video but i swear this is the best, i love all ur teaching videos

you are now my favourite math tutor sir

AND THE OUTFIT GOES CRAZY HARD!!!

I get confused when blackpenredpen uses blue pen. Other than that, keep up the good work!

The cartwheel got me good lol...

At 3:58 the legendary technique was shown

Thanks man! You're seriously the GOAT for math videos.

God bless this man.

Thank you very much! subscribed:)

Thank you

Hi Steve, do you have a video with the laplace transform differentiation theorem proof?

plz put all laplace sums in a playlist and this for all topics . thank u awesome teacher:)

You want something better? Search “Laplace marathon” and “inverse Laplace marathon” on YT and you will see it.

you are awesome. I understand this shit because of you. but yeah that cartwheel was the best part in the video. thanks again man. hopefully you do linear algebra sometimes because I'm doing that next semester lol

goated teacher

Which of the following sequences could represent the impulse response of a stable discrete-time system? k^2 (-0.65)^k 2^k ksin(k)

However, there is a formula for inverse Laplace transform of product of functions F(s)&G(s), Inverse Laplace (F(s)*G(s)) = integral from 0 to t of f(t-v)*g(v)dv (i.e, convolution of f(t)&g(t)), where F(s) & G(s) are Laplace transforms of f(t) & g(t) respectively

i wonder how it is possible to do integration by parts with three functions may it can be helpfull to show why there are is no good solution to the Problem L(f(t)g(t))=?. Can you make a proove for my question

Good vid. If you want more hits, get 'First Shifting Theorem' in the title (that's what some other books etc refer to it as).

im paying so much money to go to school and im still learning off of youtube, take my prof 2 hours to poorly try to explain what he did in 10 min

I will become you disciple someday.

yo what about L{e^-3t*f(t-4)} is it F(s+3)*e^-4s

There is not next vídeo KK KK

IIIIBallPythonsIIIII thanks but I can't view it since I don't have an account. Would u mind taking a screenshot and tweet it to me or send it to my email at blackpenredpen@gmail.com

blackpenredpen that's why I was confused. I sent u the screenshots. @gmail

I belive convolution theorm can be a direct formula to solve this: L{f(t)g(t)} = F(s)*G(s) Conversely, L{f(t)*g(t)} = F(s)G(s) However, the later form is of more practical usage in analog and digital filter design than the former form.. ☺️

my problem L {(1 / a) * e ^ (- bt / a) * f (t / a)} I could not solve
