  • Gracias.

  • this is a good video that tells how to calculate the divergence of a vector field in cartesian coordinates, but it does not say what divergence is

  • hey guess what Khan, I got a 97 on my calculus test......ALL BECAUSE OF YOU! I can't thank you enough!

  • only 1% of your viewers dislike your video....considering this is a maths video..

  • Thank you based Sal. *cries*

  • I may still pass Calculus 3 because of your incredible videos!

  • thank you

  • Just to make sure, what is the meaning of the numerical value of the divergence? You said a positive divergence means the vectors are going "outward" the region, but what makes a divergence of 1/2 different from a divergence of 1?

  • ack this part with the gradient, divergence and curls is confusing me greatly. Feels like i'm missing some videos. Cant seem to spot the difference between gradient and divergence either...

  • @Liaomiao

    gradient = del * function  => vector * scalar = vector.

    divergence = del * vectorfield => vector * vector = scalar.

  • u r just awesome...........

    

  • Thank you sir , you saved me many times.

  • Interesting, but I believe there are better indicators and methods to use in trading.

  • hey man, u've saved me...thanx a lot

  • high 5!

  • I love this guy....he reeeaaallly helps

  • cheers dude, another awesome vid.

  • thanks men.

    a lot of help for me cause i have a quiz tomorrow..

    hehehe

  • Thanks

  • it's easy to understand! thanks!

  • aha awesome video

  • So... is the divergence a scalar or a vector?

  • Its mapping a scalar field to a vector field, so i guess you can think of it as a scalar.

  • scalar

  • Thnx, so it's a scalar field in quite a few dimensions (though usually in 2 or 3) then if it's a scalar acquired from a plane, the divergence can be plotted along the axis parallel to the normal of the field from which it was acquired. This would make some sort of noisy "landscape" if I'm correct.

  • Thank you
