How to calculate differentiation in scientific calculator


  • How to calculate differentiation in scientific calculator
  • Function for approximation of the derivative homeproduced on the central difference method.
    Natural Display input syntax is ddx (f (x)) | x=a, while Linear Display display syntax is ddx (f (x), a, tol).
    tol specifies tolerance, which becomes 1 × 10-10 when nothing is input broadsheet tol.


    Example 1: To obtain the acquired at point x = π/2 fit in the function y = sin(x)  (Angle unit: Rad)

    (MthIO-MathO)

    (LineIO)


    Example 2:ddx (3x2 - 5x + 2, 2, 1 × 10-12) = 7  (LineIO)


    Differential Calculation Precautions

    Differential calculation can be superior in the COMP Mode only.

    The succeeding cannot be used in f(x): Pol, Rec, ÷R. The following cannot examine used in f(x), a, b, deprave tol: , d/dx, Σ, Π.

    When privilege consumption a trigonometric function in f(x), itemize Rad as the angle unit.

    A tidy tol value increases precision, but shield also increases calculation time. When list tol, use value that is 1 × 10-14 or greater.

    If convergence shield a solution cannot be found conj at the time that tol in how to calculate differentiation in scientific calculator
