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.

Read in the blogs more about the unique learning experience at nubtrek.

User Guide

Welcome to nubtrek.

The content is presented in small-focused learning units to enable you to
think,
figure-out, &
learn.

Just keep tapping (or clicking) on the content to continue in the trail and learn.

User Guide

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.

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.

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.

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.

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.

Starting on learning "Component form of vector addition". ;; In this page, you will learn how two vectors in component form add up.

What is the component form of a vector?

• components along x, y, and z axes
• magnitude of the vector
• directional cosines of vector

Answer is 'components along x, y, and z axes'

In the component form, two vectors are considered a i and p i. What is the result of addition of two vectors a i and p i ?

• (a+p)i

Answer is '(a+p)i'.
The magnitudes add up as two vectors are in the same direction i , that is, along x-axis.

What is the result of addition of two vectors ai+bj and p i ?

• (a+p)i+bj
• cannot be added, as the vectors are in different directions.

Answer is '(a+p)i+bj'. The magnitudes add up along the directions in parallel and the directions in perpendicular are kept separately. In this problem, in the direction of x-axis, a i and p i are given. They are added in magnitude.

What is the result of addition of two vectors a i+b j+c j and p i+q j+r k ?

• (a+p)i+(b+q)j+(c+r)k
• cannot be added, as the vectors are in different directions.

Answer is '(a+p)i+(b+q)j+(c+r)k'. The magnitudes add up along the directions in parallel and the directions in perpendicular are kept separately. In these two vectors, the components along the three axes are given in component form.

Addition of two vectors: When two vectors vec p = p_x i+p_yj+p_zk and vec q = q_x i+q_yj+q_zk are added the result is vec p + vec q = (p_x+q_x)i + (p_y+q_y)j + (p_z+ q_z)k
