The lower limit and upper limit specify the range of the solution. You can input a value or an expression as the range.

The following functions cannot be used within any of the arguments. Solve(, d2/dx2(, FMin(, FMax(, Σ(

Up to 10 calculation results can be displayed simultaneously in ListAns format.

The message “No Solution” is displayed if no solution exists.

The message “More solutions may exist.” is displayed when there may be solutions other than those displayed by SolveN.

kFirst Derivative Calculations[OPTN]-[CALC]-[d/dx]

To perform first derivative calculations, first display the function analysis menu, and then input the values using the syntax below.

<Math input/output mode>

K4(CALC)2(d/dx) f(x)ea

or

4(MATH)4(d/dx) f(x)ea

<Linear input/output mode>

K4(CALC)2(d/dx) f(x),a)

a is the point for which you want to determine the first derivative.

d/dx ( f (x), a) dxd f (a)

The derivative is defined as:

f (a + Ax) – f (a) f'(a) = lim –––––––––––––
