Study Notes

Math Vocabulary Study Notes

Addend: Refers to one of the numbers to be added in a mathematical equation to calculate the sum.
Arc: Represents a segment or portion of a curve, often used in geometry to describe parts of circles.
Asymptote: A straight line that a curve approaches as it extends towards infinity; significant in calculus for analyzing behavior of functions.
Average: The calculation obtained by dividing the total sum of a set of numbers by the quantity of numbers in that set.
Base: In geometry, it is the designated side of a geometric figure, often the side on which the figure stands.
Bisect: The action of dividing something into two equal parts, commonly used in geometry.
Chord: A line segment that connects two points on a circle, integral in various circle theorems.
Circumference: The perimeter or distance around a circle; calculated as ( C = \pi d ) or ( C = 2\pi r ).
Coefficient: A numerical factor in a term; for example, in ( 4xy ), 4 is the coefficient.
Conjugates: Refers to pairs of complex numbers or expressions that differ only in the sign of one term.
Coordinate: A number assigned to a point on a number line; essential in graphing and spatial representation.
Curve: The continuous path traced by a moving point, fundamental in both geometry and calculus.
Cycloid: The specific curve traced by a point on the circumference of a rolling circle along a straight path.
Denominator: The bottom part of a fraction which represents the total number of equal parts.
Diameter: A chord that passes through the center of a circle; it is twice the radius.
Difference: The result of subtracting one number from another; the answer to a subtraction problem.
Digit: Any symbol from 0 to 9 used in the base-10 number system.
Dividend: The number that is being divided in a division operation, e.g., in ( 10 \div 2 ), 10 is the dividend.
Divisor: A number that divides another number in a division problem.
Exponent: In exponential notation, it indicates how many times the base is multiplied by itself.
Factor: One of the numbers multiplied together to obtain a product; e.g., in ( 4xy ), the factors are 4, x, and y.
Hypotenuse: The longest side of a right triangle, opposite the right angle.
Invert: To turn something upside down, often used in mathematics to describe flipping values or fractions.
Liter: The basic metric unit for measuring volume, equivalent to 1,000 milliliters.
Logarithm: The power to which a base number is raised to obtain a certain value; essential for solving exponential equations.
Median: The middle value in a sorted list of numbers; appropriately used in statistics to find central tendency.
Midpoint: The point that is equidistant from two specified points, often used in geometry for dividing segments.
Millimeter: A metric unit equal to one-thousandth of a liter.
Numerator: The top part of a fraction that represents how many parts are being considered.
Origin: The point on a number line that is designated as zero; crucial in coordinate systems.
Parallelogram: A four-sided shape (quadrilateral) with opposite sides that are parallel and equal in length.
Perimeter: The total distance around a flat geometric figure; calculated by adding the lengths of all sides.
Polygon: A closed plane figure made up of straight line segments; classified by the number of sides they have.
Proportion: An equation stating that two ratios are equal; used for solving problems involving proportions in mathematics.
Quadrant: One of the four sections of the Cartesian coordinate system, divided by the x and y axes.
Quotient: The result obtained from dividing one number by another; answers division problems.
Radicand: The number that is located under the radical sign in radical expressions.
Radius: The distance from the center of a circle to any point on its circumference; critical for circle calculations.
Ratio: A simple comparison between two quantities, providing insight into their relationship.
Reciprocal: The inverse of a fraction, where the numerator and denominator are swapped, e.g., the reciprocal of ( \frac{1}{2} ) is ( \frac{2}{1} ).
