Our rst examples are inequalities involving the absolute value. Before anything else, we need to be sure Before anything else, we need to be sure everyone understands what the absolute value refers to.

**Lecture 1 Real Numbers Absolute Value. Real Numbers**

The absolute value function is one that you should have some familiarity, but is also a function that students sometimes misunderstand. An important observation is the absolute value is a function that performs di?erent... Of course, 1 is the absolute value of both 1 and –1, but it's also the absolute value of both i and –i since they're both one unit away from 0 on the imaginary …

**Student Lesson Absolute Value Functions TXAR**

These properties of the absolute value function follow from the de?nition of opera- tions with reals and their geometric interpretation as points of a line. 2. condition report rooming accomodation pdf inequalities with a “greater than” symbol, you should split the problem into two separate inequalities, like solving an absolute value equation. This strategy is demonstrated in Example 1.

1 Properties of the Absolute Value Function De nition: The absolute value function f(x) = jxjis de ned as follows: jxj= p x2 Theorem 1.1 jxj= ? x; x<0 x; x 0 Proof: By the Law of Dichotomy, either x<0 or x 0. Also, for all x, jxj 2= (p x 2) = x from the de nition. Taking the square root, this means that jxj= x. But jxj 0 by its de nition, because the range of the square root function is all expected value of marginal pdf y y==bxxb l Example 3 log5 125==3 because 5125 Special Logarithms 10 lnlognatural log loglogcommon log xxe xx = = where e=2.718281828K Logarithm Properties
