Currying - Motivation
... Currying is similar to the process of calculating a function of multiple variables for some given values on paper ... For example, given the function f(x,y) = y / x To evaluate f(2,3), first replace x with 2 ... Since the result is a function of y, this function g(y) can be defined as g(y) = f(2,y) = y/2 ...
Integral - Extensions - Multiple Integration
... In general, an integral over a set E of a function f is written Here x need not be a real number, but can be another suitable quantity, for instance, a vector in R3 ... Just as the definite integral of a positive function of one variable represents the area of the region between the graph of the function and the x-axis, the double integral of a positive function of two variables ... The same volume can be obtained via the triple integral — the integral of a function in three variables — of the constant function f(x, y, z) = 1 over the above mentioned region ...
Integral
... Given a function f of a real variable x and an interval of the real line, the definite integral is defined informally to be the area of the region in the xy-plane ... The term integral may also refer to the notion of the antiderivative, a function F whose derivative is the given function f ... integration is connected with differentiation if f is a continuous real-valued function defined on a closed interval, then, once an antiderivative F of f is known, the definite integral of f over that interval is ...
