Graphing calculators are powerful tools for mathematical computations, and understanding how to find the absolute value on them is crucial for various applications. This article provides a comprehensive guide on obtaining the absolute value using a graphing calculator.
Formula: The absolute value of a number is its distance from zero on the number line. Mathematically, it is denoted as |x|, where x is the number. The absolute value is always non-negative, and if x is positive or zero, |x| equals x. If x is negative, |x| is equal to the negation of x.
How to Use:
- Enter the desired number in the provided input field.
- Click the “Calculate” button to find the absolute value.
- The result will be displayed below the button.
Example: Suppose you want to find the absolute value of -7. Enter -7 in the input field, click “Calculate,” and the result will show that the absolute value is 7.
