[Grothendieck] raised algebraic geometry to a new level of abstraction...if certain mathematicians could console themselves for a time with the hope that all these complicated structures were 'abstract nonsense'...the later papers of Grothendieck and others showed that classical problems...which had resisted efforts of several generations of talented mathematicians, could be solved in terms of...complicated concepts. Binomial: A polynomial equation with two terms usually joined by a plus or minus sign. Base angles theorem proof A crystal clear proof of the base angles theorem. Geometry: The study of lines, angles, shapes, and their properties. Irrational: A number that cannot be represented as a decimal or fraction. This is a glossary of math definitions for common and important mathematics terms used in arithmetic, geometry, and statistics. Chord: A segment joining two points on a circle. Difference: The difference is the answer to a subtraction problem, in which one number is taken away from another. Factoring: The process of breaking numbers down into all of their factors. Quotient: The solution to a division problem. 4 x 3 is equal to 3 + 3 + 3 + 3. Quadratic equations ask you to find the quadratic polynomial that is equal to zero. [The paper of Eilenberg and Mac Lane (1942)] introduced the very abstract idea of a 'category' — a subject then called 'general abstract nonsense'! Schémas résumés sur les suites numériques; Schémas résumés sur le second degré; Schémas résumés sur les inégalités; Schémas résumés sur angles et trigonométrie; Alphabet grec; Etude discrète : les suites. In a proof we can use: • axioms (self-evident truths) such as "we can join any two points with a straight line segment" (one of Euclid's Axioms) • existing theorems, that have themselves been proven. Identity: An equation that is true for variables of any value. Supplementary Angles: Two angles are supplementary if their sum is equal to 180°. Polynomial: The sum of two or more monomials. Parabola: An open curve whose points are equidistant from a fixed point called the focus and a fixed straight line called the directrix. Edge: A line is where two faces meet in a three-dimensional structure. Trapezoid: A quadrilateral with exactly two parallel sides. Lines that are created to help prove a statement. 5! Algebra: The branch of mathematics that substitutes letters for numbers to solve for unknown values. Reflection: The mirror image of a shape or object, obtained from flipping the shape on an axis. Ratio: The relationship between two quantities. of a true statement is also true. Numeral: A written symbol denoting a number value. in four spatial dimensions, a collection of ten numbers is needed at each point to describe the properties of the mathematical space or manifold, no matter how distorted it may be, term: in an algebraic expression or equation, either a single number or variable, or the product of several numbers and variables separated from another term by a + or – sign, e.g. Line: A straight infinite path joining an infinite number of points in both directions. According to Hardy (1999, pp. This page was last edited on 17 September 2020, at 05:02. When the total number of values in a list is odd, the median is the middle entry. y = 4, y = 5x + 3, linear regression: a technique in statistics and probability theory for modelling scattered data by assuming an approximate linear relationship between the dependent and independent variables, logarithm: the inverse operation to exponentiation, the exponent of a power to which a base (usually 10 or e for natural logarithms) must be raised to produce a given number, e.g. ( 3, 4, 5), ( 5, 12, 13), ( 7, 24, 25), ( 8, 15, 17), etc, quadratic equation: a polynomial equation with a degree of 2 (i.e. A kind of proof in which the steps are written out in complete sentences, in -743, -1.4, -√5 (but not √-1, which is an imaginary or complex number), non-commutative algebra: an algebra in which a x b does not always equal b x a, such as that used by quaternions, non-Euclidean geometry: geometry based on a curved plane, whether elliptic (spherical) or hyperbolic (saddle-shaped), in which there are no parallel lines and the angles of a triangle do not sum to 180°, normal (Gaussian) distribution: a continuous probability distribution in probability theory and statistics that describes data which clusters around the mean in a curved “bell curve”, highest in the middle and quickly tapering off to each side, number line: a line on which all points correspond to real numbers (a simple number line may only mark integers, but in theory all real numbers to +/- infinity can be shown on a number line), number theory: the branch of pure mathematics concerned with the properties of numbers in general, and integers in particular, ordinal numbers: an extension of the natural numbers (different from integers and from cardinal numbers) used to describe the order type of sets i.e. Formed by the total number of equal length box and Whisker Plot/Chart: triangle. `` point '' at which a statement assumptions logically guarantee the conclusion which follows the...
