(1+cosx)/(sinx) = (sinx)/(1-cosx)

(1+cosx)(1-cosx)/(sinx)(1-cosx) = (sinx)/(1-cosx)

(1-(cosx)^2)/(sinx)(1-cosx) = (sinx)/(1-cosx)

((sinx)^2)/(sinx)(1-cosx) = (sinx)/(1-cosx)

(sinx)/(1-cosx) = (sinx)/(1-cosx)

Einstein's famous equation, E=mc^2, can be proven through the principles of special relativity. The equation shows the equivalence of energy (E) and mass (m) through the speed of light (c) squared, indicating that a small amount of mass can be turned into a large amount of energy. This relationship has been confirmed through various experiments and observations, showing its validity in the understanding of the universe's fundamental laws.
