# Math Help - Tensor Calculus Proof

1. ## Tensor Calculus Proof

Hi, I am studying tensor calculus and I am not too familiar with tensors currently. The question I have is:

The steps to prove that a lie derivative satisfies the usual product rule, ie it is Leibniz. Please see my attachment that shows where I am up to. It is much easier to scan this than it is to try write on a computer! I am confident I am right up to where I have marked an Astrix. From that line on I am partially confident.

Many Thanks

Chris

2. ## A thought!

I just realized that the last line I left is in the form of the product rule if you take Q = YZ (with appropriate indicies... hard to write on computer). Is that all I need to prove?????

Thanks
