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 "Dot product with a null vector". ;; In this page, you will learn about the result of vector dot product with a null vector.

What is a null vector or zero vector?

  • A vector of magnitude `0`
  • `0i+0j+0k`
  • `vec 0`
  • all the above

The answer is 'All the above'

Given the definition of dot product as
`vec p cdot vec q = |vec p||vec q|cos theta`
What is `vec p cdot (vec 0)`?

  • null vector
  • `vec p`
  • `|vec p|`
  • all the above

The answer is 'Null Vector' As `|vec 0| = 0`, the dot product is `0`.

Given the definition of dot product as
`vec p cdot vec q = p_xq_x+p_yq_y+p_zq_z`
What is `vec p cdot (vec 0)`?

  • `vec 0`
  • `vec p`
  • `p_x+p_y+p_z`
  • all the above

The answer is '`vec 0`' As all the x, y, z components of `vec 0` is `0`, the dot product is `0`.

Dot product with null vector: For any vector `vec p in bbb V`
`vec p cdot vec 0 = 0`
