It was his second article on SR in 1905 and the IV-th overall in that year.

You can simply take this integral and you'll get [tex] E = mc^2 [/tex]

[tex] \int^c_0{P dv} ; [/tex]

where [tex] P = mv\gamma [/tex]

and [tex] \gamma = \frac{1}{\sqrt{1 - (\frac{v}{c})^2}} [/tex]

[tex] \int^c_0 {\frac{mv}{\sqrt{1 - (\frac{v}{c})^2}} dv = mc^2 [/tex]
