Thought-Process to Discover Knowledge

Welcome to **nub****trek**.

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.

To make best use of nubtrek, understand what is available.

nubtrek is designed to explain mathematics and science for young readers. Every topic consists of four sections.

nub,

trek,

jogger,

exercise.

This captures the small-core of concept in simple-plain English. The objective is to make the learner to think about. continue

Trekking is bit hard, requiring one to sweat and exert. The benefits of taking the steps are awesome. In the trek, concepts are explained with exploratory questions and your thinking process is honed step by step. continue

This captures the essence of learning and helps one to review at a later point. The reference is available in pdf document too. This is designed to be viewed in a smart-phone screen. continue

This part does not have much content as of now. Over time, when resources are available, this section will have curated and exam-prep focused questions to test your knowledge. continue

In this page, learn about the distributive property of vector cross product over vector addition.

Starting on learning "vector cross product is distributive over vector addition".

What does 'distributive' mean?

- to share; to spread
- to restrict; to arrest

The answer is 'to share; to spread'

Given the definition of cross product as

`vec p xx vec q = |(i, j, k),(p_x, p_y, p_z),(q_x, q_y, q_z)|`

What is `vec p xx (vec q+vec r)`

- `vec p xx ((q_x+r_x)i+(q_y+r_y)j+(q_z+r_z)k)`
- `|(i, j, k),(p_x, p_y, p_z),(q_x+r_x, q_y+r_y, q_z+r_z)|`
- `vec p xx vec q + vec p xx vec r`
- all the above

The answer is 'all the above'.

The answer is 'all the above'.

Cross product of sum of vectors is sum of cross products with the vectors - Distributive.

Distributive Property: For any given vectors p, q, r in vector space v ;; vector p cross, (vector q + vector r, =, vector p cross vector q + vector p cross vector r.
