Line Integral Example 1

[265HITMAN265]

your waaaaayyyy too slow, people aint watching to learn how to integrate, they're watching to learn about line integral, but the explanations are superb, very intuitive :P

this video explains how radon transform work in ct scan...

thanks a ton..u made such a complicated thing as easy as it can be...

[ds409]

I'm still not getting the idea,, this is not related at all to our "Line Integral" which we take on Calculus 5. But anyway, you did a great job...

[Hiei104]

Thanku very much sir for this and so many other videos..u are a great teacher..

[078matthijs]

I had to pause the video saying that this is amazing!!!

[aorelup]

Are you God?

[Seracinfinity]

You have a real gift for teaching.

Very rare

[jadeitewu]

You Sir, are awesome.

[3omary7]

you could have used 2sintcost = sin2t

thanx man that was realy helpful

[yoguely]

Help in Arc Length and curvature O_O Taylor Polynomial expansion and little oh notation

[ayala2288]

you saved my ass

Thanks a lot. Great explanation and example. Your teaching skill is great.

hanks a lot. Great explanation and example. Your teaching skill is great.

When you plot x(t) and y(t) on the 3d graphic, the quarter circle should begin and end on the x dimension extremity and the y dimension extremity of the cube, as in the function z=xy those extremities represent x=1 and y=1.

[pmcmena1]

Do you have to put the sin(t) back in after you integrate with u substitution?

[tomasiscool]

@pmcmena1 no because he reordered the bounds to fit the u function; at the end of the video it wasn't "from t=0 to t=π/2", but rather "from u=0 to u=1".

[SiegfriedZ]

@pmcmena1 basic stuff

[Taowhr]

Why would he use blue to draw the contour on a blue surface lol

[ChrisSudlik]

Thank you so much, these videos are about to save my education. I was struggling with line and surface integrals, and some physics electromagnetic stuff, The past few videos were great, and I really get the stuff now. It is really a great thing you are doing for people.

wow when I retire, I think I am going to join khanacademy

[colorsendinginurple]

when i graduate college and make my fortune, i will donate a gazillion dollars to khan academy. sal is my favorite edumacator.

[FreezingSun14]

now i can finnaly order the right amount of wood for my circular fortress!

[MrCalhoun]

If anyone wants to visualize vector and potential fields I suggest you to go to falstadcom. There is a java applet on this page which can generate these fields.

[sponsoredwalk1]

Woo Sal!!! Yay!!

Keep the calculus/differential equations coming.

It's pretty much because of you that I am at this level now and you and, although Its just has to be done - reading proper materials and doing practice questions - getting your take on the concepts is invaluable.
