The following table shoves the two ways to evaluate equations. Type of Equation Result for Result for W Equality: g (x) = f(x) Example: x2 + y2 = r2 g (x) - f(x) x2 + y2- r2 Assignment: y = f(x) Example: A = 0.5 × b x h f(x) 0.5 × b × h y - f(x) A - 0.5 × b × h Expression: f(x) Example: x3 + 1 f(x) x3 + 1 Also stores the result in the left-hand variable, A for example. To evaluate an equation: 1. Display the desired equation. (See "Displaying and Selecting Equations" above.) 2. Press or W. The equation prompts for a value for each variable needed. (If you've changed the number base, it's automatically changed back to base 10.) 3. For each prompt, enter the desired value: If the displayed value is good, press f. If you want, a different value, type the value and press f. (Also see "Responding to Equation Prompts" later in this chapter.) The evaluation of an equation takes no values from the stack - it uses only numbers in the equation and variable values. The value of the equation is returned to the X-register. The LAST X register isn't affected. Using ENTER for Evaluation If an equation is displayed in the equation list, you can press to evaluate the equation. (If you're in the process of typing the equation, pressing only ends the equation-it doesn't evaluate it.) 6-12 Entering and Evaluating Equations File name 32sii-Manual-E-0424 Printed Date : 2003/4/24 Size : 17.7 x 25.2 cm
