... You probably felt at first like you had thrown away the familiar integers and were starting over. But no, you noticed that (n,1)+(p,1)=(n +p,1)and also (n,1)(p,1)=(np,1). Thus, the set of all rational numbers whose second coordinate is one behaves just like the integers. If we simply abbreviate the ...

... how this formula is actually found you would need to refer to a textbook on calculus. The important point is that using this formula we can calculate the gradient of y = x2 at different points on the graph. For example, when x = 3, the gradient is 2 × 3 = 6. when x = −2, the gradient is 2 × (−2) = − ...

Function of several real variables
In mathematical analysis, and applications in geometry, applied mathematics, engineering, natural sciences, and economics, a function of several real variables or real multivariate function is a function with more than one argument, with all arguments being real variables. This concept extends the idea of a function of a real variable to several variables. The ""input"" variables take real values, while the ""output"", also called the ""value of the function"", may be real or complex. However, the study of the complex valued functions may be easily reduced to the study of the real valued functions, by considering the real and imaginary parts of the complex function; therefore, unless explicitly specified, only real valued functions will be considered in this article.The domain of a function of several variables is the subset of ℝn for which the function is defined. As usual, the domain of a function of several real variables is supposed to contain an open subset of ℝn.
