Thought-Process to Discover Knowledge

Welcome to nubtrek.

Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

Starting on learning "First Principles of Vector Cross Product". ;; In this page, the vector cross product is explained in first principles.

The product where vector components in perpendicular interact is defined. Given vectors `vec p` and `vec q` as shown in figure.vector cross product first principles What is the component of `vec q` perpendicular to the `vec p`?

  • `vec a`
  • `vec b`
  • `ai+bj`
  • `bj+ai`

The answer is '`vec b`'

Given `vec q` with component `vec b` in perpendicular to `vec p` as shown in figure.vector cross product first principles The angle between the vectors is `theta`. What is `|vec b|`?

  • `|q|sin theta`
  • `|q|cos theta`
  • `|p|sin theta`
  • `|p|cos theta`

The answer is '`|q|sin theta`'

Given vectors `vec p` and `vec q` and the product between them as shown in the figure.vector cross product first principles What will be a good choice of direction of the product between components in perpendicular?

Two intersecting lines, which are not parallel, define a plane. The normal on the face of the plane describes the plane and so, the normal is taken as the direction of the product.

A plane can be described by

 •  normal which is one side of the plane, or

 •  the negative of the normal, which is the other side of the plane. vector cross product choice of directions Which one is chosen for the vector cross product `vec p xx vec q`?

The direction of the cross product `vec p xx vec q`.vector cross product standard screw direction In a standard right-handed rectangular coordinate system,
The direction in which a standard screw advances when it turns from `vec p` to `vec q`, defines the normal.

The direction of the cross product `vec p xx vec q`.vector cross product right hand thumb rule for direction In a standard right-handed rectangular coordinate system,
The direction pointed by the right thumb when fingers are curled to point from `vec p` to `vec q`, defines the normal.

Formal definition of vector cross product. vector cross product illustration
`vec p xx vec q = |p||q|sin theta hat n` where `hat n` is the normal denoting the direction of right handed rotation from `vec p` to `vec q`.

Given vectors vector p and vector q and the product between them as shown in the figure. What will be a good choice of direction of the product between components in perpendicular?;; Two intersecting lines, which are not parallel, define a plane. The normal on the face of the plane describes the plane and so, the normal is taken as the direction of the product.
A plane can be described by ;; normal which is one side of the plane or the negative of the normal which is the other side of the plane. Which one is chosen for the vector cross product vector p cross vector q?
The direction of the cross product vector p cross vector q. In the standard right-handed rectangular coordinate system, the direction in which a standard screw advances when it turns from vector p to vector q, defines the normal.
The direction of the cross product vector p cross vector q. In the standard right-handed rectangular coordinate system, the direction pointed by the right thumb when fingers are curled to point from vector p to vector q defines the normal.
Formal definition of vector cross product: vector p cross vector q = magnitude of p multiplied magnitude q sine theta multiplied n hat. Where n hat is the normal denoting the direction of right handed rotation from vector p to vector q.
Vector Cross Product is defined as the product of components in perpendicular.
Vector Cross Product: for vectors p , q in real-numbers 3 dimensional space, vector p cross vector q = magnitude of p, magnitude of q, sine theta, multiplied n hat. where n hat is the unit vector of right-handed rotation from vector p to vector q.
