Just trying to get my head around some of the formulae used in "why does E=mc2"I want to understand the workings of how the formulae were transposed.Just need an online resources to relearn how to do it.The last time I had to do this was back in 1976 for my engineering degree.Any links will be really appreciated, especially if someone has already done the steps for the specific formulae used in the book.Thanks,Steve

I don't know what you mean by needing help transposing formulae.

When you bring 1/c inside the square root sign you have to square it, i.e. (1/c)sqrt{c^{2} - v^{2}} = sqrt{(1/c^{2})[c^{2} - v^{2} ]}Try finishing the rest yourself. If you'd like to see a complete derivation of E = mc^{2} then you can see the derivation I wrote and placed on my website at: "deleted because I cannot post links"
