E.1 Solving a Nonlinear Equation
This calculator can be used to solve a single nonlinear equation of the user's choice. It requires entering the equation and a starting value.
To illustrate, consider the example equation from Chapter 7,
f(x) = tan(x) * sin(x) - 2.15 = 0.
Key in the equation as:
tan Alpha x X Sin Alpha x – 2.15 Shift Solve 1.47 (This is the starting value.) = Shift Solve
The labeled answer, x = 1.167, displays on the screen shortly.
