I think you will have to provide more explanation of your notation.Hello everyone
I have tried to solve this question but I couldn't
I know the steps but I don't know how can I apply them so could u plz help me?
the question is:
Use Richardson Extrapolation to find higher order approximations to f′(x)
based off the centred approximation D2.
(a) Find the improved approximation T33 in terms of D2(h), D2(h/2) and D2(h/4).
(b) Write aMATLABscript or function using T33 to compute f′(x) for f(x) = √xcos(x) on [π/2,4π]. Plot your result using h = 1 along with D2(h), D2(h/2), D2(h/4) and the exact solution. Turn in your script and plot.
my steps are:
However, I can't apply them and don't know how can I solve it by using Matlab ,could u plz help me?
