Q:

Determine whether the line integral of each vector field (in blue) along the oriented path (in red) is positive, negative, or zero

Accepted Solution

A:
The answer in this question that determined the line integral of each vector field in blue along the semicircular, oriented path in red is a positive, negative or zero. 
Through the graph we will determined whether the line integral of each vector field is positive negative and zero. This is the answer in this question;
-Positive
-Negative
-Zero
-Negative
-Zero
-Zero
