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} ).

  • Rhombus: A specific type of parallelogram with all sides equal in length.

  • Variable: A symbol, often a letter, used in mathematics to represent an unknown or changeable number.

  • Volume: The measure of space occupied by a three-dimensional object, expressed in cubic units.
