To exit SOLVE: A

Important: • Depending on what you input for the initial value

(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 Law, so even if there

are multiple solutions, only one of them will be returned. • Due to

limitations in Newton’s Law, solutions tend to be difficult to obtain for

equations like the following:

y = sin( x ), y = e

, y =

, y = x

−1

• If an

expression does not include an equals sign (=), SOLVE produces a

solution for expression = 0.
