Rhombus: Definition, Properties, Area, Perimeter, Examples

What Is Rhombus Geometry has some type of shape. Especially in plane geometry, one type of quadrilateral is rhombus. Specifically, rhombus is special type of parallelogram that has four sides that has same length. It is like square, but the angles in rhombus need not be right angles. Beside that it is also has diagonals

Logarithmic: Definition, Functions & Rules, Examples

Definition of Logarithmic Functions Logarithmic and exponential function has close relation. It is because logarithmic inverse of exponential function. Any exponential function can be changed to be logarithmic function and any logarithmic function can be changed to be exponential function. For example there is exponential function x = ay, so the logarithmic function is alog

Even and Odd Numbers

Even Numbers Any integer that can be divided exactly by 2 is an even number. The last digit is 0, 2, 4, 6 or 8 Example: −10, -4, 0, 8, and 32 are all even numbers Odd Numbers Any integer that cannot be divided exactly by 2 is an odd number. The last digit is 1, 3,

Cardinal and Ordinal Numbers Chart

Definitions A Cardinal Number is a number that says how many of something there are, such as 1, 2, 3, 4. An Ordinal Number is a number that tells the position of something in a list, such as 1st, 2nd, 3rd, 4th. Most ordinal numbers end in “th” except for: one ⇒ first (1st) two

Set Symbols

Set Symbols – A Set is a collection of things, usually numbers. We can list each element or member of a set inside curly brackets like this: {2, 4, 6, 8, … } Three dots means goes on forever (infinite) Common Symbols Used in Set Theory Symbols save time and space when writing. Here are

Negative Exponents

Definitions Exponents are also called Powers or Indices The exponent of a number says how many times to use the number in a multiplication. General form of exponent an tells you to use a in a multiplication n times Those are positive exponents How About Negative Exponents? Dividing is the inverse (opposite) of Multiplying. A negative exponent

Partial Derivatives: Definition, How to Find, Chain Rule, Examples

Derivative is one of mathematics operation especially in calculus. In real life it uses to determine the slope, maximum or minimum of something (income, profit, etc.). What is Partial Derivative? Partial derivative is one of way to solve derivative specific problem. In detail, the problem is more than one variable function. In other words, if

Prisms: Definition, Properties, Types, Surface Area, Volume, Examples

Prisms has many types depends on the base. There are many daily things in prisms such as aquarium, tent, tissue box, cupboard, etc.. Definition of Prisms Prisms is three-dimensional shape that is bordered by two bases and lateral planes. Number of lateral planes is same with number of edges of the base. Consequently, type of

Frequency Distribution

Frequency is how often something occurs. Definition of Frequency Distribution We can make a Frequency Distribution table by counting frequencies. So, Frequency Distribution means: values and their frequency (how often each value occurs). Learn More Stem and Leaf Plots Percentage Change Quartiles Discrete and Continuous Data Data Index

Cross Multiply

To cross multiply is to go from this: To a × d = b × c How Does it Work? Multiplying the top (numerator) and bottom (denominator) of a fraction by the same amount doesn’t change its value. So, To cross multiply: Multiply the top and bottom of the left side fraction by the bottom
