5. To solve the equation, press > or O.
• This displays the solution for x on the Result tab. Details
about the values in the cell at the current cursor location are
shown in the lower-right corner of the window.
* When S > [ π Result] is turned on, display is in and π form when possible (decimal form when not
possible). When S > [ π Result] is turned off, display is in decimal form.
Note
• If the equation has multiple solutions, the number of solutions is displayed to the right of the solution.
Example: Solution of x
Higher-order equation calculations may not produce accurate results or cause an error when the
equation has multiple solutions.
• If the equation has an imaginary solution, the solution is displayed in the form specified by the S >
[Complex Mode] setting.
• S key operation is ignored on the Result tab. Operate the S key on the Editor tab.
Using Solver
You can find the value of any variable in the equation without having to solve the equation by transforming or
organizing the equation.
Example: Suppose an object is thrown into the air with initial velocity V and reaches height H after T time.
Use the equation below to determine initial velocity V when H = 14 (m) and T = 2 (seconds), and
gravitational acceleration G = 9.8 (m/s
H = VT − 1

2. On the Type tab, select [Solver] and then press > or O.
3. On the Setup tab, enter the equation into the Eq line.
4. Press O.
• This displays a list of variables included in the equation.
5. Specify for which of the variables you want to solve.
(1) Press O to display the Solve for dialog.
(2) To obtain initial speed V, select [V] and then press O.
6. Sequentially input H=14, T=2, and then G=9.8.
