Question

Given vectors u = (-8,-5) and

v = (-1, -2), find the sum u + v and write
the result in component form.

Answer 1

u + v = < - 9, - 7 >

Explanation:

to sum u and v add the corresponding x and y components of the 2 vectors

u + v

= < - 8, - 5 > + < - 1, - 2 >

= < - 8 - 1, - 5 - 2 >

= < - 9, - 7 >
