Hi, I was just wondering how an eroding dune and a non-eroding dune would differ, in terms of diagrams. For example, is there any site that would compare two cross-sectional shapes of the dunes? I couldn't find any on google.

what would be the differentiation of 2^3^x^2? so that is 2 to the 3 to the x to the 2... each is an exponent of one other... the answer i got is 2^3^x^2 * ln 2 * 3^x^2 * x^2 * 2x is that right? my friend had the same, except she did not have x^2 in it. pl...
