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.

Complex Number Conjugate

»  Conjuage of a+ib
Conjugate means "coupled or related". Conjugate of a complex number makes the number real by addition or multiplication.

→  =bar(a+ib)
→  =a-ib

Starting on learning "Conjugate of a complex number". ;; In this page, Conjugate of a complex number is explained.

In numerical expressions or algebraic expressions, we can manipulate the expressions without modifying the value of the expression
•  add and subtract : eg 3 = 3+1-1
•  multiply and divide : eg : 3 = 3 xx 2/2
•  etc.

. These manipulations help to arrive at a different form of expressions or help to solve.

In case of complex numbers, a+ib, one modification stands out "convert the complex number to real number". This can be achieved either by addition or multiplication with the number a-ib.
•  addition (a+ib) + (a-ib) = 2a
•  multiplication (a+ib) xx (a-ib) = a^2+b^2

For a given complex number z= a+i b, the connected number that give a real number on multiplication is a-ib. It is named as conjugate of z and represented as bar(z) or bar(a+ib) = a-ib

What does 'conjugate' mean?

• coupled; joined ; related in reciprocal or complementary
• disjoint; additional; unrelated and orthogonal

The answer is 'coupled; joined ; related in reciprocal or complementary'

bar(z) is called ... of z.

In numerical expressions or algebraic expressions, we can manipulate the expressions without modifying the value of the expression ;; add and subtract : for example 3 = 3+1 minus 1;; multiply and divide : for example : 3 = 3 multiplied by 2 divided by 2 ;; et cetera. ;; These manipulations help to arrive at a different form of expressions or help to solve. ;; In case of complex numbers, a+i b, one modification stands out ; convert the complex number to real number. This can be achieved either by addition or multiplication with the number a minus i b. ;; addition (a+i b) + (a minus i b) = 2a ;; multiplication (a+ib) multiplied by (a minus ib) = a squared +b squared
For a given complex number z= a+i b, the connected number that give a real number on multiplication is a minus i b. It is named as conjugate of z and represented as ;; conjugate of z or; conjugate of a+i b =; a minus i b
