Chapter 10: Q 24. (page 801)

Find u+vand u-v. Also sketchu,v,u+vand u-v.

role="math" localid="1649578020551" u=3,-4andv=-1,5

Short Answer

Expert verified

The required value isu+v=2,1andu-v=4,-9.

Step by step solution

01

Step 1. Given information.  

We have given vector

u=3,-4andv=-1,5

02

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

u+v=x1+x2,y1+y2=3+-1,-4+5=3-1,-4+5=2,1

and

u-v=x1-x2,y1-y2=3--1,-4-5=3+1,-4-5=4,-9

03

Step 3. Sketch u,v, u+v and u-v.

The graph of vectoru+v.

The graph of vector u-v.
