6 Entering and Evaluating Equations How You Can Use Equations You can use equations on the HP 33s in several ways: 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 where 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 | N z 2.5 ! z 16 z 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 33s 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: |H Display: Description: Selects Equation mode, shown or the current equation by the EQN annunciator.
