I just discovered this absolutely insane identity, am I the next oiler? sqrt(1/2) vs sqrt(2)/2

Did you know that sqrt(1/2) is actually the same as sqrt(2)/2, where sqrt means "the square root"? I will show you the algebraic approach, called the "rationalizing the denominator," to see how sqrt(1/2)=sqrt(2)/2, and I will also talk about why we do it!
