Short Answer

Expert verified

The angle of v is 60o.

Step by step solution

01

Step 1. Given information  

We have been given a vector v=i+3j.

We have to find its direction.

02

Step 2. Write the formula 

The angle between the vector and complex axisi is given as

α=tan-1ba

03

Step 3. Substitute the values 

α=tan-131α=tan-13α=60o
