WebWhen integrating, a dummy variable is one that "disappears completely in the final result." For example, in the expression ∫ x d x, x is not a dummy variable because the expression is equivalent to x 2 2 + c, that is, the x hasn't "disappeared." If we had replaced x with, say, y, then the result would change (to y 2 2 + c ). WebThe most common way to represent a function is by giving an explicit formula to compute the image under the function written using some variable x and then f(x) denotes the image of x under f. Thus in equation (1) the symbol x in f(x) and in dx is dummy. It serves no other purpose than to represent the function.
