Chapter 1, Problem 1.41E

Given two vectors $\stackrel{\to }{A}=-\text{2}\text{.00 }\hat{i}+\text{ 3}\text{.00 }\hat{j}\text{ + 4}\text{.00 }\hat{k}$ and $\stackrel{\to }{B}=3.\text{00 }\hat{i}+\text{ 1}\text{.00 }\hat{j}-\text{ 3}\text{.00 }\hat{k}$, (a) find the magnitude of each vector; (b) use unit vectors to write an expression for the vector difference $\stackrel{\to }{A}-\stackrel{\to }{B}$; and (c) find the magnitude of the vector difference $\stackrel{\to }{A}-\stackrel{\to }{B}$. Is this the same as the magnitude of $\stackrel{\to }{B}-\stackrel{\to }{A}$? Explain.
