• Since the SOLVE function uses Newton's Method, cer-
tain initial values (assumed values) can make it impos-
sible to obtain solutions. In this case, try inputting an-
other value that you assume to be near the solution and
perform the calculation again.
• The SOLVE function may be unable to obtain a solution,
even though a solution exists.
• Due to certain idiosyncrasies of Newton's method, solu-
tions for the following types of functions tend to be diffi-
cult to calculate.
Periodic functions (i.e.
Functions whose graph produce sharp slopes (i.e.
x
e y x
, = 1/
Discontinuous functions (i.e. y = x )
• If an expression does not include an equals sign (=), the
SOLVE function produces a solution for expression = 0.
