Mathematical standard libraries now include a large collection of mathematical functions, such as mathematical rounding, mathematical calculations, exponential, logarithmic, and tigonometric functions, and much more.
Mathematical Sequences are listings of numbered objects. Expressed in more detail a mathematical sequence describes a mapping of the natural numbers onto a (sub) set of the real numbers. In a sequence, exactly one real number is assigned to each natural number. These real numbers form the terms of the sequence.
