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

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 "Modulus of a complex number". ;; Complex numbers are ordered pair of real numbers and a modulus is defined for that. This page explains the modulus of a complex number in detail.

A Complex number a+i b is represented on complex plane as shown in the figure. What is the length of the line segment between origin and the point represented by the complex number?

• sqrt(a^2+b^2)
• a+i b
• a+b

The answer is 'sqrt(a^2+b^2)'

The length of the line segment OP is called modulus of the complex number. It is represented as |z| |z| is called modulus of z or mod z.

What does "modulus" mean?

• absolute measure without any additional information
• mathematical model

In complex number, the absolute measure of the number without splitting into the real or imaginary parts is modulus.

|z| is called...

The answer is 'Modulus or mod'.
