Example Question #661 : Multiple Integration

Possible Answers:

Correct answer:

Explanation:

Example Question #1 : Line Integrals

Evaluate , where , and  is any path that starts at , and ends at .

Possible Answers:

Correct answer:

Explanation:

Since there isn't a specific path we need to take, we just evaluate  at the end points.

 

Example Question #2 : Line Integrals

Use Green's Theorem to evaluate , where  is a triangle with vertices  with positive orientation.

Possible Answers:

Correct answer:

Explanation:

First we need to make sure that the conditions for Green's Theorem are met. 

The conditions are met because it is positively oriented, piecewise smooth, simple, and closed under the region (see below).  

In this particular case , and , where , and  refer to .

We know from Green's Theorem that

 

So lets find the partial derivatives.

 

 

 

Example Question #2 : Green's Theorem

Use Green's Theorem to evaluate the line integral

over the region R, described by connecting the points , orientated clockwise.

Possible Answers:

Correct answer:

Explanation:

Using Green's theorem

since the region is oriented clockwise, we would have

which gives us

Example Question #3 : Green's Theorem

Use Greens Theorem to evaluate the line integral

over the region connecting the points  oriented clockwise

Possible Answers:

Correct answer:

Explanation:

Using Green's theorem

 

Since the region is oriented clockwise

Example Question #1551 : Calculus 3

Evaluate , where  is the upper half of the sphere .

Possible Answers:

Correct answer:

Explanation:

Since we are only dealing with the upper half of a sphere, we can determine the boundaries easily, and remember to convert to spherical coordinates.

Example Question #1 : Gradient Vector, Tangent Planes, And Normal Lines

Find the equation of the tangent plane to  at .

Possible Answers:

Correct answer:

Explanation:

First, we need to find the partial derivatives in respect to , and , and plug in .

 

Remember that the general equation for a tangent plane is as follows:

Now lets apply this to our problem
