Relativity?

Question

From the two assumptions that Special Relativity makes
1.) The laws of physics are the same in all inertial frames of reference. In other words, there are no privileged inertial frames of reference.
2.)Invariance of c - The speed of light in a vacuum is a universal constant, c, which is independent of the motion of the light source.

make a full theoretical derivation of the Lorentz factor, time dilation, mass and length dilation, and prove that E=m*c^2.

or at least say how one would go about doing this and not be a jerk like dogsafire.

Answer 1

Some guy already did that a few decades ago.
