Input an initial value for X (Here, input 1):
Note
• During the time from when you press
pressing , you should use Linear Display input procedures for input.
Important!
• Depending on what you input for the initial value for X (solution variable), SOLVE may
not be able to obtain solutions. If this happens, try changing the initial value so they
are closer to the solution.
• SOLVE may not be able to determine the correct solution, even when one exists.
• SOLVE uses Newton's method, so even if there are multiple solutions, only one of
them will be returned.
• Due to limitations in Newton's method, solutions tend to be difficult to obtain for
equations like the following: y = sin(x), y = e
