109• Solve uses Newton’s method to calculate approximations. The following cansometimes occur when this method is used.—Solutions may be impossible to obtain for certain initial estimated values.Should this happen, try inputting another value that you assume to be inthe vicinity of the solution and perform the calculation again.—The calculator may be unable to obtain a solution, even though a solutionexists.• Due to certain characteristics of Newton’s method, solutions for the followingtypes of functions tend to be difficult to calculate.—Periodic functions (i.e. y = sinx – a)—Functions whose graph produce sharp slopes (i.e. y = e x, y = 1 / x)—Inverse proportion expressions and other discontinuous functions.Solve Calculations 7 - 4
