## What is the z component of a vector parallel to the XY plane?

When a plane is parallel to the xy-plane, for example, the z-coordinate of each point in the plane has the same constant value. Only the x– and y-coordinates of points in that plane vary from point to point. that is parallel to the yz-plane.

**What does it mean when a vector is parallel to the YZ plane?**

Vector Parallel to yz -Plane: The yz -plane has equation x=0 , so all vectors that are parallel to the yz -plane must be orthogonal to the normal vector of that plane (x=0) , in other words, they must be perpendicular to the vector ^i=⟨1,0,0⟩ i ^ = ⟨ 1 , 0 , 0 ⟩ .

### Is curl positive clockwise?

A rotating sphere on a rod gives z-component of curl. This rotation means that the component of the curl in the z direction is positive (using the right hand rule). If the sphere were rotating clockwise when viewed from the positive z-axis, then the component of the curl in the z direction would be negative.

**What is the vector of the YZ plane?**

A vector in the “yz-plane” has the form <0, y, z>. Further, two vectors are perpendicular if and only if there dot product is 0. will be perpendicular to <0, x, y> if and only if by+ cz= 0. For example, is perpendicular to <0, y, z>.

## How do you find the direction vector of a plane?

Vector Representation. A vector in a plane is represented by a directed line segment (an arrow). The endpoints of the segment are called the initial point and the terminal point of the vector. An arrow from the initial point to the terminal point indicates the direction of the vector.

**What is the direction vector?**

Definition of a vector. A vector is an object that has both a magnitude and a direction. Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. The direction of the vector is from its tail to its head.

### What is the correct representation of curl of a vector?

The curl of a vector field A, denoted by curl A or ∇ x A, is a vector whose magnitude is the maximum net circulation of A per unit area as the area tends to zero and whose direction is the normal direction of the area when the area is oriented to make the net circulation maximum!.

**Which line is parallel to the x z axis?**

Every line parallel to the xz axis has the form r ( t) = ( x 0, y 0, z 0) + ( a, 0, c) t. Note that, v → ⋅ j → = ( a, 0, c) ⋅ ( 0, 1, 0) = 0. Ie, the vector j is orthogonal director vector r. Therefore, r is parallel to the x z plane. Thanks for contributing an answer to Mathematics Stack Exchange!

## Is the vector j parallel to the x z plane?

Ie, the vector j is orthogonal director vector r. Therefore, r is parallel to the x z plane. Thanks for contributing an answer to Mathematics Stack Exchange! Please be sure to answer the question. Provide details and share your research! But avoid … Asking for help, clarification, or responding to other answers.

**How do you find the curl of a vector field?**

Given the vector field →F = P →i +Q→j +R→k F → = P i → + Q j → + R k → the curl is defined to be, curl →F = (Ry −Qz)→i +(P z −Rx)→j +(Qx−P y)→k curl F → = (R y − Q z) i → + (P z − R x) j → + (Q x − P y) k → There is another (potentially) easier definition of the curl of a vector field.

### What is the -dot product of normal vector and direction vector?

-dot product of plane’s normal vector and the direction vector of the line must equal zero as the line is perpendicular to the normal vector -line doesn’t lie on plane, meaning one must choose a point that’s not on that plane
