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 this section weâre going to be taking a look at the precise, mathematical definition of the three kinds of limits we looked at in this chapter. Weâll be looking at the precise definition of limits at finite points that have finite values, limits that are infinity and limits at infinity. Weâll also give the precise, mathematical definition of continuity. Letâs start this section out with the definition of a limit at a finite point that has a finite value. Definition 1 Let f(x) be a function defined on an interval that contains, except possibly at.
