[OPTN][F4](CALC)[F3]d(d/dx)f(x)[,]a[,][tol[)]d(a: differential coefficient point , tol: tolerance) (vddx(f(x),a)ddxf(a) Quadratic differential calculations produce an approximate differential value using the following second order differential formula, which is based on Newton's polynomial interpretation. Quaf(a)=2f(a+3h)27f(a+2h)270f(a+h)490f(a)+270f(ah)27f(a2h)2f(a3h)180h2In this expression, values for sufficiently small increments of h are used to obtain a value that approximates f(a).

Other variables (A through Z excluding X, r, G) 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. ##Specify tolerance (tol) value of 114 or less. An error (Time Out) occurs whenever no solution that satisfies the tolerance value can be obtained.
