2-5-3 Numerical Calculations Example To determine the derivative at point x = 3 for the function y = x3 + 4 x2 + x - 6, with a tolerance of "tol" = 1E - 5 Input the function f(x). AK4(CALC)2(d/dx)vMd+evx+v-g, Input point x = a for which you want to determine the derivative. d, Input the tolerance value. bE-f) w A4(MATH)4(d/dx)vMde +evx+v-ged w # In the function f(x), only X can be used as a variable in expressions. Other variables (A through Z excluding X, r, θ) are treated as constants, and the value currently assigned to that variable is applied during the calculation. # Input of the tolerance (tol) value and the closing parenthesis can be omitted. If you omit tolerance (tol) value, the calculator automatically uses a value for tol as 1E-10. # 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. # In the Math input mode, the tolerance value is fixed at 1E-10 and cannot be changed. # 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 2007501401
