equations

Definition of equations in English English dictionary: Students will be expected to write balanced (their highlighting, not mine) equations and should be encouraged to show state symbols Ionic equations should be used where appropriate (like redox reactions and electrolysis, to name two) The use of [H] and [O] to show reducing and oxidising agents in equations in organic (ie not inorganic or physical) chemistry is acceptable (note that acceptable is not the same as good or excellent or 'the best chemistry I've seen since Bobby Boyle started messing around with gases'); plural of equation; a statement that two expressions are equal

Maxwell's equations: Four equations, formulated by James Clerk Maxwell, that together form a complete description of the production and interrelation of electric and magnetic fields. The statements of these four equations are (1) electric field diverges from electric charge, (2) there are no isolated magnetic poles, (3) electric fields are produced by changing magnetic fields, and (4) circulating magnetic fields are produced by changing electric fields and by electric currents. Maxwell based his description of electromagnetic fields on these four statements
equation: A statement showing the equality of two expressions usually separated by left and right signs and joined by an equals sign
equation: a mathematical statement that says that two expressions have the same value
equation: Two expressions, separated by an equals sign (=) For example y = x + 3 is an equation
equation: {i} making equal; statement demonstrating the equality of two quantities (Mathematics); equally balanced state
equation: In astronomy, a small correction to observed values to remove the effects of systematic errors in an observation
equation: an algebraic statement that has an equal sign
equation: A symbolic statement that can be used to do a calculation For example, x = 12y, where x is the number of inches in y feet
equation: An equation is a mathematical statement saying that two amounts or values are the same, for example 6x4=12x2
equation: the act of regarding as equal a mathematical statement that two expressions are equal
equation: a state of being essentially equal or equivalent; equally balanced; "on a par with the best"
equation: two algebraic expressions that are set equal to each other
equation: the act of regarding as equal
equation: An equation is a situation in which two or more parts have to be considered together so that the whole situation can be understood or explained. The equation is simple: research breeds new products New plans have taken chance out of the equation. see also equate. Statement of equality between two expressions consisting of variables and/or numbers. In essence, equations are questions, and the development of mathematics has been driven by attempts to find answers to those questions in a systematic way. Equations vary in complexity from simple algebraic equations (involving only addition or multiplication) to differential equations, exponential equations (involving exponential expressions), and integral equations. They are used to express many of the laws of physics. See also system of equations. algebraic equation chemical equation continuity equation difference equation differential equation Drake equation Green Bank equation integral equation Laplace's equation motion equation of ordinary differential equation partial differential equation quadratic equation Schrödinger equation state equation of Maxwell's equations system of equations simultaneous equations
equation: A quantity to be applied in computing the mean place or other element of a celestial body; that is, any one of the several quantities to be added to, or taken from, its position as calculated on the hypothesis of a mean uniform motion, in order to find its true position as resulting from its actual and unequal motion
equation: A statement that two mathematical expressions are equal, such as: 3x + y = 7
equation: An equation is a math sentence that says that 2 things are equal An equation always has an equal (=) sign The thing or things that are on the left side of the equal sign are equal to the things on the right side of the equal sign Here are a few equations: X = Y + 5 A = B - 4 Z = 3 A C = D (circumference of a circle) A = W H (area of a rectangle with width W and height H) E = M C2 (Einstein's famous equation) In the first equation, if Y is 2, then X must be 2 + 5 or 7 to make the equation true In the second equation, if B is 10, then A must be 6 to make the equation true In the third equation, the number next to the letter means multiply the value of the variable represented by "A" by 3 So if A is 4, then Z must be 12 to make the third equation true Now here's a problem for you: In the first equation, if Y were 10, what would X be?
equation: An assertion that two expressions are equal, expressed by writing the two expressions separated by an equal sign; from which one is to determine a particular quantity
equation: a mathematical expression containing an equals sign The expression on the left hand side of the equals sign must have the same value as the expression on the right hand side Equations often contain algebra
equation: a statement that shows two expressions having the same value
equation: An equation is a statement of equality between two algebraic expressions with one or more unknowns (See also system of equations ) Linear equation in one unknown: 3x -1 = 5 To solve 3x - 1 = 5 3x = 6 x = 2 (root/solution) Quadratic equation in one unknown: x2 - x - 2 = 0 To find the solution of x2 - x - 2 = 0 (x - 2)(x + 1) = 0 x - 2 = 0 x + 1 = 0 x = 2 x = -1 (solutions) Linear equation in two unknowns: 2x + y = 3

maxwell's equations: four differential equations that summarize classical properties of electromagnetic fields
simultaneous equations: a set of equations in two or more variables for which there are values that can satisfy all the equations simultaneously
system of equations: or simultaneous equations In algebra, two or more equations to be solved together (i.e., the solution must satisfy all the equations in the system). For a system to have a unique solution, the number of equations must equal the number of unknowns. Even then a solution is not guaranteed. If a solution exists, the system is consistent; if not, it is inconsistent. A system of linear equations can be represented by a matrix whose elements are the coefficients of the equations. Though simple systems of two equations in two unknowns can be solved by substitution, larger systems are best handled with matrix techniques
