The area is how much paint you would need to paint it If you have a fixed perimeter you can consider having a fence, and ask how big of a area it would surround. You can have a really really long length and a very short height like a piece of spaghetti versus a square which would have a much larger area Note in a calculus class you can take the derivative of the area function given a fixed perimeter, and you can calculate the maximum area you can get.

Fixed area would be the inverse saying that you can get a bunch of different what is mkv file type even if you keep the area constant. I'm not sure what you mean by fixed perimeter and fixed area, but I can define perimeter and area. Trending News. USC's Song Girls have an ugly yet familiar story.

A common error is to assume that a triangle that has a fixed perimeter must also have a fixed area. This is definitely not the case as can be seen from the figure above. As you drag the orange point A, the triangle will maintain a fixed perimeter. But as you can see, the area varies quite a bit. The amount of space inside the boundary of a flat (2-dimensional) object such as a triangle or circle, or surface of a solid (3-dimensional) object. These shapes all have the same area of 9: Help . 1 day ago · Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. It only takes a minute to sign up. I'm currently working on the problem of finding the function with minimum arc length when the area between itself and the x-axis is fixed.

This is a glossary of common mathematical terms used in arithmetic, geometry, algebra, and statistics. Abacus : An early counting tool used for basic arithmetic. Absolute Value : Always a positive number, absolute value refers to the distance of a number from 0. Addend : A number involved in an addition problem; numbers being added are called addends. Algebra : The branch of mathematics that substitutes letters for numbers to solve for unknown values.

Algorithm : A procedure or set of steps used to solve a mathematical computation. Angle : Two rays sharing the same endpoint called the angle vertex.

Angle Bisector : The line dividing an angle into two equal angles. Area : The two-dimensional space taken up by an object or shape, given in square units. Array : A set of numbers or objects that follow a specific pattern. Attribute : A characteristic or feature of an object—such as size, shape, color, etc.

Average : The average is the same as the mean. Add up a series of numbers and divide the sum by the total number of values to find the average. Base : The bottom of a shape or three-dimensional object, what an object rests on. Base 10 : Number system that assigns place value to numbers. Bar Graph : A graph that represents data visually using bars of different heights or lengths.

Bell Curve : The bell shape created when a line is plotted using data points for an item that meets the criteria of normal distribution. The center of a bell curve contains the highest value points. Binomial : A polynomial equation with two terms usually joined by a plus or minus sign.

Calculus : The branch of mathematics involving derivatives and integrals, Calculus is the study of motion in which changing values are studied. Capacity : The volume of substance that a container will hold. Centimeter : A metric unit of measurement for length, abbreviated as cm. Circumference : The complete distance around a circle or a square. Chord : A segment joining two points on a circle. Coefficient : A letter or number representing a numerical quantity attached to a term usually at the beginning.

Common Factors : A factor shared by two or more numbers, common factors are numbers that divide exactly into two different numbers. Composite Number : A positive integer with at least one factor aside from its own. Composite numbers cannot be prime because they can be divided exactly. Cone : A three-dimensional shape with only one vertex and a circular base. Conic Section : The section formed by the intersection of a plane and cone.

Constant : A value that does not change. Coordinate : The ordered pair that gives a precise location or position on a coordinate plane. Congruent : Objects and figures that have the same size and shape. Congruent shapes can be turned into one another with a flip, rotation, or turn. Cosine : In a right triangle, cosine is a ratio that represents the length of a side adjacent to an acute angle to the length of the hypotenuse.

Cylinder : A three-dimensional shape featuring two circle bases connected by a curved tube. Decimal : A real number on the base ten standard numbering system. Denominator : The bottom number of a fraction.

The denominator is the total number of equal parts into which the numerator is being divided. Diagonal : A line segment that connects two vertices in a polygon. Diameter : A line that passes through the center of a circle and divides it in half.

Difference : The difference is the answer to a subtraction problem, in which one number is taken away from another. Digit : Digits are the numerals found in all numbers. Dividend : A number being divided into equal parts inside the bracket in long division. Divisor : A number that divides another number into equal parts outside of the bracket in long division. Edge : A line is where two faces meet in a three-dimensional structure.

Ellipse : An ellipse looks like a slightly flattened circle and is also known as a plane curve. Planetary orbits take the form of ellipses. End Point : The "point" at which a line or curve ends. Equilateral : A term used to describe a shape whose sides are all of equal length. Equation : A statement that shows the equality of two expressions by joining them with an equals sign.

Expressions : Symbols that represent numbers or operations between numbers. Face : The flat surfaces on a three-dimensional object. Factor : A number that divides into another number exactly. Factoring : The process of breaking numbers down into all of their factors.

Factorial Notation : Often used in combinatorics, factorial notations requires that you multiply a number by every number smaller than it. The symbol used in factorial notation is! When you see x! Factor Tree : A graphical representation showing the factors of a specific number. Fibonacci Sequence : A sequence beginning with a 0 and 1 whereby each number is the sum of the two numbers preceding it. Figure : Two-dimensional shapes. Finite : Not infinite; has an end. Flip : A reflection or mirror image of a two-dimensional shape.

Formula : A rule that numerically describes the relationship between two or more variables. Fraction : A quantity that is not whole that contains a numerator and denominator.

Geometry : The study of lines, angles, shapes, and their properties. Geometry studies physical shapes and the object dimensions. Graphing Calculator : A calculator with an advanced screen capable of showing and drawing graphs and other functions.

Graph Theory : A branch of mathematics focused on the properties of graphs. Greatest Common Factor : The largest number common to each set of factors that divides both numbers exactly. The greatest common factor of 10 and 20 is Hexagon : A six-sided and six-angled polygon.

Histogram : A graph that uses bars that equal ranges of values. Hyperbola : A type of conic section or symmetrical open curve. The hyperbola is the set of all points in a plane, the difference of whose distance from two fixed points in the plane is a positive constant.

Hypotenuse : The longest side of a right-angled triangle, always opposite to the right angle itself. Identity : An equation that is true for variables of any value. Integers : All whole numbers, positive or negative, including zero. Irrational : A number that cannot be represented as a decimal or fraction. A number like pi is irrational because it contains an infinite number of digits that keep repeating. Many square roots are also irrational numbers. Isosceles : A polygon with two sides of equal length.

Kilometer : A unit of measure equal to meters. Knot : A closed three-dimensional circle that is embedded and cannot be untangled. Like Fractions : Fractions with the same denominator. Line : A straight infinite path joining an infinite number of points in both directions.
