Write a program to create an ordered collection ''A'' of functions of a real number. At least one function should be built-in and at least one should be user-defined; try using the sine, cosine, and cubing functions. Fill another collection ''B'' with the inverse of each function in ''A''. Implement function composition as in [[Functional Composition]]. Finally, demonstrate that the result of applying the composition of each function in ''A'' and its inverse in ''B'' to a value, is the original value. <small>(Within the limits of computational accuracy)</small>. |
