This "relativistic kinetic energy" equation makes no sense to me
Presently, I'm reading an e-book I found on the internet titled "Relativity: The Special and General Theory", which may or may not have been written by Albert Einstein. Here's the part which has me in deep patatoes:
The author then mentions developing the equation into a series. I just can't understand how the second equation can represent kinetic energy.
Also, what's the difference between an equation and formula?

In accordance with the theory of relativity the kinetic energy of a material point of mass m is no longer given by the well−known expression:
1/2 mv^2
but by the expression:
mc^2 / (squareroot)1 - v^2/c^2
The author then mentions developing the equation into a series. I just can't understand how the second equation can represent kinetic energy.
