6 Entering and Evaluating Equations How You Can Use Equations You can use equations on the HP 32SII in several way: For specifying an equation to evaluate (this chapter). For specifying an equation to solve for unknown values (chapter 7). For specifying a function to integrate (chapter 8). Example: Calculating with an Equation. Suppose you frequently need to determine the volume of a straight section of pipe. The equation is V = .25 π d2 l There d is the inside diameter of the pipe, and l is its length. You could key in the calculation over and over, for example, .25 š { M y 2.5 z : y 16 y calculates the volume of 16 inches of 2 1/2-inch diameter pipe (78.5398 cubic inches). However, by storing the equation, you get the HP 32SII to "remember" the relationship between diameter, length, and volume-so you can use it many times. Put the calculator in Equation mode and type in the equation using the following keystrokes: Keys: { G Display: Description: Selects Equation mode, or the or the current equation current shown by the EQN annunciator.
