Coordinate transforms

  1. Sep 27, 2009 #1
    Hey, im having trouble understanding how you can transform one set of coordinates into another using partial derivatives i just dont get the whole thought process behind it. I came across this while reading about covariant and contrivariant vectors. If anyone can help clear up how this works i would really appreciate it. Also if i need to be more specific about what i mean or if you would like to see an example of what im talking about just ask and i would be happy to post it up.

    Hi Storm Butler! :wink:
    We don't use partial derivatives for the transformation itself, we can only use them for a very local transformation, or for transforming the d part in an integral: ∫∫∫dx dy dz = ∫∫∫ (jacobian) da db dc.

    see http://en.wikipedia.org/wiki/Jacobian_matrix_and_determinant" [Broken] for some details. :smile:
