Definition Expanded Notation is about Writing a number to show the value of each digit. Expanded Notation is shown as a sum of each digit multiplied by its matching place value (ones, tens, hundreds, etc.) Examples 1,234 = 1 × 1,000 + 2 × 100 + 3 × 10 + 4 × 1 98,765 = 9 ×
Definition Rational Function is A function that is the ratio of 2 polynomials. It is Rational because one polynomial is divided by the other polynomial, like a ratio. (Note: the denominator cannot be zero.) Examples Learn More FOIL Method Counting Numbers Difference Multiplicative Inverse Definitions Index
Definition When 2 lines are crossed by another line (Transversal): Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. How to remember the angle pairs are on Alternate sides of the Transversal, and they are on the Exterior of
Definition When two lines are crossed by another line (Transversal): Alternate Interior Angles are a pair of angles on the inner side of each of those 2 lines but on opposite sides of the transversal. How To remember: The angle pairs are on Alternate sides of the Transversal, and they are on the Interior of
By combining these 2 function into 1 function, we have performed function composition, which is the focus of this section. Definition of Function Composition Function composition is a method to combine existing functions. Another method is to carry out the usual algebraic operations on functions, including addition, subtraction, multiplication, & division. We do this by
What Is Quadrilateral Quadrilateral is two-dimension shape that closed and has four sides. It come from latin words, “quadri” means four and “lateral” means sides. The internal angle is 360°. In real life, there are many things that has quadrilateral shape. For example: table top, book, picture, kite, envelope, etc. Quadrilateral Properties There are two
What Is Independent Event? Independent means not relate with something/someone. For examples of independent condition are buying a chocolate and finding a pencil on the road, writing a letter and sweeping the floor, etc. The events in examples of independent condition are not relate each other. It is not causal relationship between of them. Probability
Definitions Just an easy way to remember how Sine, Cosine and Tangent work: Soh… (Sine = Opposite / Hypotenuse) …cah… (Cosine = Adjacent / Hypotenuse) …toa (Tangent = Opposite / Adjacent) Right Triangle Firstly, the names Opposite, Adjacent and Hypotenuse come from the right triangle: “Opposite” is opposite to the angle θ “Adjacent” is adjacent (next to) to
About Fibonacci (The Man) His real name was Leonardo Pisano Bogollo. He lived in Italy between 1170 and 1250. “Fibonacci” was his nickname, which roughly means “Son of Bonacci”. Fibonacci was not the first to know about the sequence, it was known in India hundreds of years before! As well as being famous for the Fibonacci
A quadratic is a type of problem In mathematics that deals with a variable multiplied by itself (an operation known as squaring). It derives from the area of a square being its side length multiplied by itself. The word quadratic comes from “quadratum”, which means square in Latin word. There are a lot of phenomena in the real world that can be
