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
x
, y =
x.
