Chapter 10: Q 25. (page 801)

Find $u + v a n d u - v$ also sketch $u, v, u + v, u - v$
role="math" localid="1649595165778" $u = (1, - 2) a n d v = (- 3, 6)$

Short Answer

Expert verified

The required value of $(u + v) = (- 2, 4) a n d (u - v) = (4, - 8)$ .

Step by step solution

Step 1. Given information.

We have given vector $u = (1, - 2) a n d v = (- 3, 6)$

Step 2. Find the values of u+v and u-v.

$u + v = (x_{1} + x_{2}, y_{1} + y_{2}) = (1 + (- 3), - 2 + 6) = (1 - 3, - 2 + 6) = (- 2, 4)$

and

$u - v = (x_{1} - x_{2}, y_{1} - y_{2}) = (1 - (- 3), - 2 - 6) = (1 + 3, - 2 - 6) = (4, - 8)$

Step 3. Sketch u , v u+v and u-v

The graph of vector $u + v$ .

The graph of vector $u - v$ .
