Solution 34847: Using the fMin( ) Function on the TI-83 Plus and TI-84 Plus Family of Graphing Calculators.

How do I use the fMin( ) function on the TI-83 Plus and TI-84 Plus family of graphing calculators?

The fMin( ) function returns the value of variable where the local minimum of expression occurs, between lower and upper, with specified tolerance. Reference the example provided below.

The syntax for the fMin( ) function is: fMin(expression,variable,lower,upper[,tolerance])

Example: Find the function minimum of sin(A), for the variable A, with -p for the lower bound and p for the upper bound.

1) From the main screen press [MATH] then [6] to select 6:fMin(
2) Press [SIN] [ALPHA] [A] [)] [,] [ALPHA] [A] [,] [(-)] [2ND] [p] [,] [2ND] [p] [)] and [ENTER] to display the results.



Please see the TI-83 Plus and TI-84 Plus Family guidebooks for additional information.
