equation, in mathematics, a statement, usually written in symbols, that states the equality of two quantities or algebraic expressions, e.g., x+3=5. The quantity x+3, to the left of the equals sign (=), is called the left-hand, or first, member of the equation, that to the right...

•4x + 10y – 2 is not anequation, because it does not consist of equals sign. It is only an expression. 查看更多回答 Q:What does 'equation' mean on the definition below by Longman dictionary? "the set of different facts, ideas, or people that all affect a situation and must be ...
Let $(G, \cdot)$ be a group, $(H, +)$ be an Abelian group, and $f:G\rightarrow H$ be a function. In this paper, for a positive integer n, we first give a representation of nth-order Cauchy difference of f via the function as $$ C^{(n)}f(x_{1},x_{2},\ldot

A parabola is a plane curve that is formed when a point moves such that the distance between it and a fixed point equals the distance between it and a fixed line in the Cartesian plane. The fixed point is the focus of the parabola, and the fixed line is the directrix of the parabola...
A trigonometric equation identity is a trigonometric equation that is held to be true. Think of these as your regular equations. They have an equals sign and are assumed to be true. Think about what it means to be an equation. Doesn't it mean that the two sides are always equal? Yes,...
To solve an equation in mathematics, you must first find its solutions, which are the values (numbers, functions, sets, and so on) that satisfy the condition stated in the equation, which is usually made up of two expressions linked by an equals sign. One or more variables are designated...
We can see that the modulus of the initial value u ( x , 0 ) = 1.01233 sech ( x ) exp ( 0.0990195 i ln a ( x ) ) (57) asymptotically equals zero as | x | ≥ 10 . Thus, u ( x , t ) can be negligible outside Ω , and we can set u ( x , t ) = 0 for x...
