Crazy Representations of Natural Numbers from 0 to 10000 Using Cubic Function

This work brings natural numbers from 0 to 10.000 written in two different forms. Increasing and decreasing orders of 1 to 9 and 9 to 1. This is done using cubic function along with basic operations. In some cases, square-root and factorial are also used. Previously, the author also worked with numbers up to 300.000 using only basic operations along with square-root, factorial, etc. For more details refer author's work in reference list.  Similar kind of work is given with Triangular numbers, Fibonacci sequence values and square function. This kind of work using cubic function is never seen before. Not all the representations are by use of cubic function.
