The exponent on the variable portion of a term tells you the "degree" of that term. For instance, the power on the variable ,x, in the leading term in the above polynomial is 2; this means that the leading term is a "second-degree" term, or "a term of degree two".The second term …
Let f be a function with domain D in R, the real numbers, and D is an open set in R. Then the derivative of f at the point c is defined as: f'(c) =lim as ,x,-> c of the difference quotient [f(,x,)-f(c)]/[,x,-c] If that limit exits, the function is ,called, differentiable at c.
The slope-intercept form of a linear equation is y = mx + b. In the equation, ,x, and y are the variables. The numbers m and b give the slope of the line (m) and the value of y when ,x, is 0 (b). The value of y when ,x, is 0 is ,called, the y-intercept because (0,y) is the point at which the line crosses the y axis.
Algebraic Expression 1. Algebraic Expression: Any expression that contains letters, numbers and basic operation signs +, --, × and ÷ is ,called, an Algebraic Expression. Examples: 2x, 5y, -20p, 3x + 5y, -9q/8 are a few examples of algebraic expressions.. In the above examples, ,x,, y, p, q are the letters and 2, 5, -20, -9/8 are the numbers, while the symbols: -, +, ÷ are the basic (fundamental ...
The horizontal axis is ,called, the ,x,-axis. The vertical axis is ,called, the y-axis. The point where the ,x,-axis and y-axis intersect is ,called, the origin. The numbers on a coordinate grid are used to locate points. Each point can be identified by an ordered pair of numbers; that is, a number on the ,x,-axis ,called, an ,x,-coordinate, and a number on ...
Integration, ,in mathematics,, technique of finding a function g (,x,) the derivative of which, Dg (,x,), is equal to a given function f (,x,). This is indicated by the integral sign “∫,” as in ∫ f (,x,), usually ,called, the indefinite integral of the function. The symbol dx represents an infinitesimal displacement along ,x,; thus…
The composite functions of higher ,math, often use h(,x,) and g(,x,), in combination,,defining which comes first, and which is second. The substitution is bad enough, but using y's would make it worse.. In summary, feel free to immediately use "y =" instead of "h(,x,)", if it clarified the problem.
Matrix, a set of numbers arranged in rows and columns so as to form a rectangular array. The numbers are ,called, the elements, or entries, of the matrix. Matrices have wide applications in engineering, physics, economics, and statistics as well as in various branches of ,mathematics,. Historically, it
which makes the function-argument status of ,x, clear, and thereby implicitly the constant status of a, b and c. Since c occurs in a term that is a constant function of ,x,, it is ,called, the constant term.: 18. Specific branches and applications of ,mathematics, usually have specific naming conventions for variables.
