quantity - the concept that something has a magnitude and can be represented in mathematical expressions by a constant or a variable argument - a variable in a logical or mathematical expression whose value determines the dependent variable; if f(x)=y, x is the independent variable experimental ...
In the derivation, removing y-average trick, a higher order term of stream function including five arbitrary functions and forced topography is introduced. Taking the strict solution of the standard constant coefficient KdV equation as the initial value, the approximate analytical solution of the ...
A coefficient is an integer that is multiplied with the variable of a single term or the terms of a polynomial. Learn all about the coefficient of a variable in this article along with examples and practice questions.
Identify the math term described. The result of addition. If f(x) is a linear function, which statement must be true: A) f(x) has no constant term. B) f(x) has no x^2 term. C) f(x) has no terms with a coefficient other than 1. D) f...
