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.

User Guide    

nub is the simple explanation of the concept.

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

User Guide    

trek is the step by step exploration of the concept.

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

User Guide    

jogger provides the complete mathematical definition of the concepts.

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

User Guide    

exercise provides practice problems to become fluent in the concepts.

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

Starting on learning "the vector cross product does not have multiplicative identity".

What does 'identical' mean?

  • same; similar; alike
  • different; mismatch

The answer is 'same; similar; alike'

What is the multiplicative identity in real numbers - number system?

  • `1`
  • `0`
  • `-1`

The answer is '`1`'.

For any real number `a`, `a xx 1 = a`, so `1` is the multiplicative identity in real numbers.

Given that `vec p xx vec q` is perpendicular to `vec p` for any `vec q`, is there a vector `vec r` such that `vec p xx vec r = vec p`?

The answer is "1". For any real number a, a multiplied 1 = a. So, 1 is the multiplicative identity in real numbers.
Given that vector p cross vector q is perpendicular to vector p for any vector q, is there a vector vector r such that vector p cross vector r = vector p?
No multiplicative identity for Cross Product.
Cross Product does not have a Multiplicative Identity: For any vector p in vector space v, there is no other vector such that cross product between them in vector p.
