Does Δ(Δx)/Δ(Δy) exist in mathematics and physics?
Try an example as see what happens. Say x=t3 and y=t4Sorry. I should say:
I mean that Δ(Δx)/Δ(Δy) does not have any physics or mathematical meaning. Do you agree? If not, can you tell me what is the meaning of Δ(Δx)/Δ(Δy)? Sure, you can do any calculation as you want.
