• Input of the tolerance (tol) value and the closing parenthesis can be omitted. • Specify a tolerance (tol) value of 1E-14 or greater. An error (Time Out) occurs whenever no solution that satisfies the tolerance value can be obtained. • The rules that apply for linear differential also apply when using a quadratic differential calculation for the graph formula (see page 2-24). • Inaccurate results and errors can be caused by the following: - discontinuous points in x values - extreme changes in x values - inclusion of the local maximum point and local minimum point in x values - inclusion of the inflection point in x values - inclusion of undifferentiable points in x values - differential calculation results approaching zero • You can interrupt an ongoing quadratic differential calculation by pressing the key. • Always use radians (Rad mode) as the angle unit when performing trigonometric quadratic differentials. • You cannot use a differential, quadratic differential, integration, 3, maximum/minimum value, Solve, RndFix or logab calculation expression inside of a quadratic differential calculation term. • With quadratic differential calculation, calculation precision is up to five digits for the mantissa. • In the Math input/output mode, the tolerance value is fixed at 1E-10 and cannot be changed. I Integration Calculations [OPTN]-[CALC]-[°dx] To perform integration calculations, first display the function analysis menu and then input the values using the syntax below. *(CALC)* (°dx) f(x) a b tol (a: start point, b: end point, tol: tolerance) f(x), a, b, tol) b f (x)dx a * fx-7400GII: (CALC) b Area of f(x)dx is calculated a As shown in the illustration above, integration calculations are performed by calculating integral values from a through b for the function y = f (x) where a x b, and f (x) 0. This in effect calculates the surface area of the shaded area in the illustration. 2-26
