Chapter 3, Problem 6Q

To determine

To describe:

 Two vectors $\overrightarrow{\mathrm{a}}$ and $\overrightarrow{\mathrm{b}}$ such that

$\overrightarrow{\mathrm{a}}+\overrightarrow{\mathrm{b}}=\overrightarrow{\mathrm{c}}\mathrm{ }\mathrm{a}\mathrm{n}\mathrm{d}\mathrm{ }\mathrm{a}+\mathrm{b}=\mathrm{c}$

$\overrightarrow{\mathrm{a}}+\overrightarrow{\mathrm{b}}=\overrightarrow{\mathrm{a}}-\overrightarrow{\mathrm{b}}$

$\overrightarrow{\mathrm{a}}+\overrightarrow{\mathrm{b}}=\overrightarrow{\mathrm{c}} \mathrm{a}\mathrm{n}\mathrm{d}\mathrm{ }{\mathrm{a}}^2+{\mathrm{b}}^2={\mathrm{c}}^2$
