Thought-Process to Discover Knowledge

Welcome to **nub****trek**.

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.

Welcome to the *novel approach to understanding complex numbers: it completely changes the way complex numbers are thought-about and learned*.

• Irrational numbers are numerical expressions, eg: `2+root(5)(3)`

» Complex numbers are numerical expressions too.

• Irrational numbers do not have a standard form. They are expressed as numerical expressions, with some having many terms. eg: `2+ root(2)(2)-3xx root(3)(5)`

» Similar to irrational numbers, the direct extension is to express complex numbers as numerical expressions. eg: `x^3=1` has `3` solutions, `(root(3)(1))_(1st)`, `(root(3)(1))_(2nd)`, `(root(3)(1))_(3rd)`

» But, Any complex number is given in a standard form `a+ib`, because of Euler Formula `re^(i theta)``= r(cos theta + i sin theta)`

How so? Go through the first few lessons to get the *astoundingly new perspective* of complex numbers. *(click for the list of lessons in this topic)*

Properties of Complex Number Arithmetic

Complex number system is an extension of Real number system with inclusion of a new number `i=sqrt(-1)`. The complex arithmetic has the * properties mostly identical* to real arithmetic. The additional features are related to modulus, argument, and conjugate.

Learn these in a *simple-thought-process*.
