how to calculate the fifth derivative of a function in matlab

To calculate the fifth derivative of a function in Matlab, you can use the following syntax:

main.m
syms x                   % define symbolic variable x
f(x) = sin(x);           % define the function to differentiate
df = diff(f, 5);         % calculate the fifth derivative of f

Here, syms creates a symbolic variable x, and f(x) defines the function to differentiate (in this case, sin(x)). The diff function is then used to calculate the fifth derivative of f, which is stored in the variable df.

Note that the resulting fifth derivative will also be a symbolic expression, which can be evaluated for specific values of x using the subs function.
