Finding 4 Vectors in the Same Plane & Direction

In summary, the conversation discusses how to find three other vectors in the same plane as a given vector, with the same magnitude, direction, and slope. The method of finding these vectors involves adding the coordinates of a chosen point to the initial and terminal points of the given vector.

If i given a terminal and initial points of a vector in x,y,z positive plane . how to find three other vectors in the same plane having the same magnitude and the same direction and the same slope ?

Imagine what that vector looks like in 3-space. What would the coordinates of the vector's initial and terminal points be if you shifted it over 1 in the x-direction? The y-direction? What would the magnitude and direction of such a vector be?

thank you sethric for reply, but can not i calculate those vectors without drawing ?
 
  • #4
Are you given the plane separately from the vector?
 
  • #5
the question gives just the initial and terminals points of the vector , nothing else. and thank you for reply.

I don't know what you mean by the "xyz positive plane". A vector doesn't determine a plane.

If what you want is just another vector having the same length and direction as the one from P to Q, just pick any (p,q,r) and add its coordinates to P's and Q's coordinates to get P' and Q'. Then the vector P'Q' will work.

Related to Finding 4 Vectors in the Same Plane & Direction

1. How do you determine if four vectors are in the same plane and direction?

To determine if four vectors are in the same plane and direction, you can use the dot product. If the dot product of any two vectors is equal to zero, then the vectors are perpendicular and cannot lie in the same plane. If the dot product of all possible pairs of vectors is equal to zero, then the vectors are in the same plane.

2. What is the significance of finding four vectors in the same plane and direction?

Finding four vectors in the same plane and direction is important in physics and engineering as it allows us to solve problems involving forces, motion, and equilibrium. It also helps in visualizing and understanding complex systems.

3. Can four vectors be in the same plane but not in the same direction?

Yes, it is possible for four vectors to lie in the same plane but not in the same direction. This means that the vectors are coplanar, but they have different orientations or magnitudes.

4. What is the mathematical representation of four vectors in the same plane and direction?

The mathematical representation of four vectors in the same plane and direction is a linear combination of three vectors, also known as the span of the vectors. A linear combination is a sum of scalar multiples of vectors.

5. How can you use the cross product to determine if four vectors are in the same plane and direction?

You cannot directly use the cross product to determine if four vectors are in the same plane and direction. The cross product only applies to two vectors in three-dimensional space. However, you can use the cross product to find the normal vector of the plane in which the four vectors lie. If all four vectors are parallel to this normal vector, then they are in the same plane and direction.
