I have attached a photo of a page from a book that I am studying. The author is showing a derivation of E(ave) = kT(adsbygoogle = window.adsbygoogle || []).push({});

However, I can't follow this derivation. He says that you need to use integration by substitution and I am OK with that. But when he actually does the substitution it looks wrong. Where there is uv - int vdu , he seems to have left out E in the first term. He also seems to have left out a negative sign. Then the E suddenly pops up again in the second term, int v du and then he says limit e^-E/kT = 0, as E becomes 0. Is that correct? I thought it became 1, or am I completely off the mark? Thanks
