Any function and its inverse are symmetrical about the line\(y = x\).

THE object of the authors of this volume of mathematical tables is “to supply a comprehensive set of tables of the numerical values of the elementary functions which are in constant use in mathematics ...

Composite functions are made when the output from one function is used as the input of another function. The names of the functions are written next to each other, with the function that is used first ...

Let Fn be a free group of rank n with free basis x1, ⋯, xn. Let {y1, ⋯, yk} be a set of k ≤ n elements of Fn, where each yi is represented by a word Yi(x1, ⋯, xn) in the generators xj. Let ∂ yi/∂ xj ...
