However, $400,000 is the president's base salary. He also gets a $50,000 expense account for job-related expenses, a $100,000 travel account and a $19,000 entertainment account.resident Bush currently earns $400,000 per year, along with a $50,000 expense account, a $100,000 nontaxable travel account, and $19,000 for entertainment.[2] The president's salary and total expense account serve as an unofficial cap for all other federal officials' salaries, such as that of the Chief Justice  |}.
Limits at Infinity. Limits at infinity truly are not so difficult once you've become familiarized with then, but at first, they may seem somewhat obscure. The basic premise of limits at infinity is that many functions approach a specific y-value as their independent variable becomes increasingly large or small.
In mathematics, a limit is the value that a function or sequence approaches as the input or index approaches some value. Limits are essential to calculus (and mathematical analysis in general) and are used to define continuity, derivatives, and integrals. The concept of a limit of a sequence is further generalized to the concept of a limit of a topological net, and is closely related to limit and direct limit in category theory. In formulas, a limit is usually written as. and is read as the limit of f of n as n approaches c equals L .
