1. Find the curl of the vector field F at the indicated point:

The curl of the vector field is

So at (2, -1, 3) the curl is

2. Evaluate the following line integral using the Fundamental theorem of line Integrals:

Suppose that C is a smooth curve given by , . Also suppose that f is a function whose gradient vector, , is continuous on C. Then,

So first we need to find the function whose gradient vector is

Now we differentiate f(x, y) respect to y:

Where c is constant.

So

Thus, the line integral is
