Chapter 10: Q 26. (page 801)

Find u+vandu-valso sketch u,v,u+v,u-v

u=4,0andv=0,3

Short Answer

Expert verified

The required value ofu+v=4,3andu-v=4,-3.

Step by step solution

01

Step 1. Given information.  

We have given vectoru=4,0andv=0,3.

02

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

u+v=x1+x2,y1+y2=4+0,0+3=4,3

and

u-v=x1-x2,y1-y2=4-0,0-3=4,-3

03

Step 3. Sketch u, v, u+v and u-v.

The graph of vector u+v.

The graph of vector u-v.
