Hello, Originally Posted by Jensen I was asked execute the proof shown in figure 1. I managed to prove what is in figure 2, but cannot make any headway on figure 3. Please Help. Remember that $\displaystyle \frac{d(x^2)}{dx}=2x$ And hence $\displaystyle x \cdot dx=\frac{d(x^2)}{2}$
Thanks for the help. I also found a vector identity that worked nicely also.
