Example Question #661 : Multiple Integration
Example Question #1 : Line Integrals
Evaluate , where , and is any path that starts at , and ends at .
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.
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.
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
Using Green's theorem
Since the region is oriented clockwise
Example Question #1551 : Calculus 3
Evaluate , where is the upper half of the sphere .
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 .
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
