Chapter 1: Before You Get Started

•Note that, as the variable R already has a number stored in memory, the calculator recalls that number.

• indicates that there is another variable earlier in the expression.

4.Press 8 to input the radius.

Input of all variables is now complete.

5.Press e to obtain the solution.

•The answer (volume of cone ￿) is displayed on the third line.

6.Press e and 8 to input the height for cone ￿.

•The display returns to a value entry screen with ‘8’ substituted for ‘10’ in variable H.

7.Press e to confirm the change.

8.Press 9 to enter the new radius then press e to solve the equation.

•The volume of cone ￿ is now displayed.

•In any step, press @ h to obtain the solution using the values entered into the variables at that time.
