Question

derive propagation of error in multiplication​

Answer 1

Answer:

• The examples use the propagation of errors using average deviations. Usually Δx≪x and Δy≪y so that the last term is much smaller than the other terms and can be neglected. The same rule holds for multiplication, division, or combinations, namely add all the relative errors to get the relative error in the result.
