In Problems 47鈥�52, find the unit vector in the same direction asv:v=i-jv=i-j

Short Answer

Expert verified

The unit vector in the same direction asvis12i-12j.

Step by step solution

01

Step 1. Magnitude of the Vector

The given vectorv=i-j

Th magnitude of the given vector is 1+1=2

02

Step 2. Unit Vector in the direction of v
