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.

This captures the small-core of concept in simple-plain English. The objective is to make the learner to think about. continue

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

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

Complex multiplication is distributive over complex addition.

Starting on learning "Distributive Property". ;; In this page, you will learn that the complex multiplicative is distributive over complex addition.

What does 'distribute' mean?

- to share; to spread
- to restrict; to arrest

The answer is 'to share; to spread'

Consider three complex numbers `z_1, z_2, z_3 in CC`, and the following

add first `z_2+z_3` and multiply that by `z_1`.

multiply `z_1 xx z_2` and `z_1 xx z_3` and added the results.

Will they give the same result?

- Yes, the results will be the same
- No, the results will differ

The answer is "Yes, the results will be the same".

The complex numbers addition and multiplication is considered to be operations on numerical expressions of real numbers.

Given `z_1 = a_1+ib_1`, `z_2 = a_2+ib_2`, and `z_3 = a_3+ib_3`. What is `z_1 xx (z_2 + z_3)`?

- `z_1 xx z_2 + z_1 xx z_3`
- `z_1 xx z_2 + z_3`

The answer is '`z_1 xx z_2 + z_1 xx z_3`'

`z_1 xx (z_2 + z_3)`

`quad quad = z_1 xx z_2 + z_1 xx z_3`

proof:

`z_1 xx (z_2 + z_3)`

`quad quad = (a_1+ib_1) xx (a_2+a_3 + i (b_2+b_3))`

`quad quad = a_1a_2-b_1b_2 + i(a_1b_2+a_2b_1) `

`quad quad quad quad +a_1a_3-b_1b_3 + i(a_1b_3+a_3b_1)`

`quad quad = z_1 xx z_2 + z_1 xx z_3`

to restrict; to arrest

The answer is 'to share; to spread'

Consider three complex numbers z_1, z_2, z_3 in CC , and the following

add first z_2+z_3 and multiply that by z_1 .

multiply z_1 xx z_2 and z_1 xx z_3 and added the results.

Will they give the same result?

add first z_2+z_3 and multiply that by z_1 .

multiply z_1 xx z_2 and z_1 xx z_3 and added the results.

Will they give the same result?

yes;s;same

Yes, the results will be the same

no;differ

No, the results will differ

The answer is "Yes, the results will be the same".

The complex numbers addition and multiplication is considered to be operations on numerical expressions of real numbers. ;; Given z1 = a1+i b1, z2 = a2+i b2, and z3 = a3+i b3. What is z1 multiplied, z2 + z3?

1

z1 into z2 + z1 into z3

2

z1 into z2 + z3

The answer is 'z1 into z2 + z1 into z3'

z1 into, z2 + z3 ;; equals z1 into z2 + z1 into z3 ;; proof: z1 into, z2 + z3 ;; equals a1+i b1 xx, a2+a3 + i b2+b3 ;; equals a1 a2-b1 b2 + i a1 b2+a2 b1 +a1 a3-b1 b3 + i a1 b3+a3 b1 ;; equals z1 multiplied z2 + z1 multiplied z3

Product with sum of complex numbers is the sum of, products with the complex numbers- distributive.

Distributive Property of Complex Numbers: For any given complex numbers z1, z2, z3 in complex numbers ;; z1 multiplied, z2 + z3 ;; equals z1 multiplied z2, + z1 multiplied z3

Given z1 z2= 3+4i, and z2 z3=1-3i what is z1+z3, multiplied by z2?

1

2

3

4

minus 5i

The answer is ' 4+i '
