Laplace/Step Function Differential Equation

[dickfigures0722]

thanks for all the help I really appreciate it. : )

[PerpetualEpiphany]

@aureliusenzo it's supposed to be in a form consistent with the definition of the heaviside function

[alexwhb122]

after taking the partial fraction you for get what day it is... I have never heard truer words. lol

[lambertwei]

Thank you for everything. You have taught me lots of knowledge. :)

[MrMymusicality]

Very very hairy....

[taltor727]

thanks a lot Sal!! All of these problems with the partial fractions are hairy. Even the ones you can get away with completing the square on can get hairy when doing the algebra to match the Laplace Inverse Transform table.

Epic

[aureliusenzo]

Sine (2 t) = Sine (2 (t - 2 pi))

[aureliusenzo]

Sine t = Sine (t - 2 pi)

Great series, but you missed a major simpification at the end of this video

I have four 8am lectures for this subject this semester. It is so much easier learning this stuff in my own time (rather than at 8am) and I also consider you better than my current maths lecturer. Also, the fact that I can pause and rewind just tops it off. You are doing an amazing thing, many thanks from USYD, Sydney Australia

thankyou so much amazing video

[Myevilstyle]

I hate myself for finding you so late.

[amaz789]

EPIC PROBLEM

[Sawer89]

thank you man :)

[HarvestWain]

dieses video ist der hammer! sal, du bist mir ein held!

[thamathmatic]

clear and straight forward...good color too

[wcygena]

this video really helps me a lot. i was really confused about this type of questions since I don't really get how it works from class. thanks so much for the video.

gonna have exam next week. and the videos you posted are so great i should say.

:)

[hifhif123]

what if the given boundary conditions are something like y(2) and y'(4), can laplace transforms still be used to solve differential equations then??

[LureAngler]

Thank you. Your voice have helped many around the world. =)

[Werwolf2x]

hm can't you just write just sin(t) instead of sin(t-2*PI) since sin and cos stay the same after shifting by 2*PI?

other than that, the video is really amazing ^^

[sxtaco]

i love you.

[akatsuki5565]

You made a complicated, hairy problem looked really simple. Thank you so much.

[khounslow]

oh my god yes

[MrU2BE4U]

Thanks Sal. :-)

Anyone else put on some J-dilla beats in the background when watching khan academy

[adrianorula]

Thank you bro. You helped me a lot. We spend like 2 hours trying to understand that kind of unit step funcion applyied to Laplace transform.

Sorry for some grammar mistake. English isnt my first language. Im from Brazil and would like to thank you

[RFMaroja]

Thank you a lot, you've just clarified my mind!

from brazil!

[mwm48]

...how come i can rarely get ANY of your videos to display more than blank screen, this seems to happen more often than not. does anyone have any info on how to resolve this problem? :(

btw, the videos that decided to work were very informative, especially since my professor's English is kinda rough, thanks for the vids!

[nicohavuelto]

Epic Problem FTW

[kyfriednura]

you talk wayyy to much! helpful. but the side comments really wasted my time

[matt3DRC]

Thanks Sal, everything was great but you forgot to put the ending parentheses when you rewrote the differential after you did the partial fractions. :)

[marktwain0591]

you are the best maths teacher i have come across...cheers..:)

[titanjo87]

u the man

[LanesAccount]

great help.. helped my decomp skills alot!

[shortstopsick]

I dont know who is better at teaching this,my professor or you. Nevermind you r, after every confused lesson, i come to your videos and i actually understand,thanks

[3point1four1five9]

You just saved my weekend! Thank you so much!

[PrinceFX]

We do appreciate it a lot! Thanks a bunch!

[concussiona2f]

we do appreciate it very much, thank you... 12:50

I have never understood how to eat three pie in a certain amount of time, T, while subtrating ten pies from the total amount of pies, P, eaten during T. BUT NOW I UNDERSTAND!

shouldnt D = -1/3 not positive 1/3?

[erdembenek]

a great lecture.thank you

[solo2wolf]

I do indeed appreciate it :). Fantastic teaching style, thanks for sharing it.

[grimshawr]

I had it until about 16:50. Oh, by the way Sal, in the last year I have picked up a math and a physics minor thanks to you.
