Given vectors [math]\vec{u} = \langle –4, 6 \rangle[/math] and [math]\vec{v} = \langle 8, –1 \rangle[/math], find the vector sum [math]\vec{u} + \vec{v}[/math] in three ways:
[math]\,\,\,\,\,[/math]a. [math]\,\,[/math]by placing them head-to-tail
[math]\,\,\,\,\,[/math]b. [math]\,\,[/math]by using the Parallelogram Rule
[math]\,\,\,\,\,[/math]c. [math]\,\,[/math]by using component-wise addition
