can anyone help me with this function, please?

find numerical derivative of f(x) = tan−1(?) at x = 2 using central difference scheme where is x is in radians. Use different values of step size h in central difference scheme and compare with true value of the derivative by plotting error for the different h. f(x) means function of x.

Here are some Numerical difference formulas using the central difference method (substitute dt = h).

You can find more formulas with even higher accuracy on wikipedia. (see "numerical differentiation" and also "finite difference coefficient"
