If a number couldn't be expressed in p/q form where p,q are real numbers and q in non-zero, the number is said to be an irrational number .To simplify the fraction we should rationalize the denominator. Rationalizing the denominator can aid you to simplify certain equations. This could be done by the following listed methods -
I added addition and subtraction of matrices with examples, I fixed and added to the definition, I added and put examples of how to get the position of a number in a matrix, I added a few more pictures, and I added a very basic way of multiplication of matrices.
* Elaborated on more cases of factorising equations
-I decided to add other cases of factorising other algebraic equations that involves different values of the quadratic equation apart from 1
* Removing unnecessary <br> tags
-I decided to extend the amount of information on Pythagoras Theorem, through explaining other cases of finding an unknown side apart from the hypotenuse, which are the perpendicular height and base.
* Added content to stub
Gave definition, examples, two methods to compute as well as a JavaScript algorithm, and some generalizations.
* Removed content
Removed external links and added internal links to FCC guide pages when possible.
* Equation symbol changes and formatting changes
-Initially, SQRT(value) does not actually create a square root symbol, so I decided to use replace SQRT( ) with √ next to the number, which has successfully created the square root symbol to the left of the number.
-Given that the information of the article was unorganized through jumbled information, I decided to use the paragraph tag, <p>, to make the article have an organized structure.
-I also used the biggest headline tag, <h1>, to outline the topics of square roots
-Given that '-----' was not an effective method of creating fractions, I decided to use the fraction slash tag, "⁄", the superscript element, <sup>, and the subscript element, <sub>, in order to create suitable fractions
* Removing unnecessary coding and editing content
-I just double checked this content, and realized that there were a couple of mistakes such as an extra heading, putting a square root as sqrt(3) instead of √3, and adding unnecessary paragraph tags instead of extra spaces.
Fixed copy/pasting(?) typos, also changed the 'because' in each example to explain the why instead of just showing it's true for a single number, not mentioning any others. (Proof by example is very, very, VERY bad to encourage.)
Presented formula, derived it and gave examples, one simple and one more involved to show how it's not always 'easy' or 'obvious' how this rule can be applied to help, a rule of thumb in how to use it and a brief list of generalizations.
* Introduced Geometric progression
* Fixed some typos and added geometric mean
* fixed some more typos
* Added Design Patterns book
* added design pattern books
Errors fixed, and added a few other minor points to clarify things, some examples, and more rules for differentiation. Also removed hot-linked images since it is sometimes frowned upon (people should not frown upon FCC!) and some don't work anymore.
replace existing text with the following new text "Divide the top of the fraction (the numerator) by the bottom of the fraction (the denominator); then multiply the result by 100 to obtain the number in percentage form. Example: Step 1: 1/4 = .25 Step 2: .25 x 100 = 25% In this example, we have determined that 1/4 equals 25%."
add text "An example of positive correlation would be the relationship between people's height and weight: taller people tend to be heavier. If we look at the average data for a large group of people, as height increases so does weight."
