Calculation of errors in product value

[musilj]

I am stuck on a seemingly easy one, how can I quote/state the error in a product of numbers for example(x1,x2,x3) with errors +/- 0.5, +/- 0.4, +/- 0.35

If you believe class propagation of errors, you can RSS the errors.

The propagation of errors was discussed a couple of years ago in the "Statistics in Engineering" forum. See thread962-92738 for the results of the discussion.
