Good day,I am trying to learn on how to use octave. I am trying to solve factorials and second order differentiation. Can you please assist on how to put it on the software. Fir example, i want to solve n! With n between 1 and 10. Where n!=1×2×3.....×(n-1)×n. For the second order, f"=f(x+h)-2f(x)+f(x-h)/h^2. With h-0
clear all
q=factorial(5)
#for second order diff
x=.4
f=@(x) sin(x)
h=linspace (1e-2, 2e-5,10)
y=(f(x+h)-2*f(x)+f(x-h)) ./(h .^2)
plot(h,y)
#this show how the approximation gets better as h gets smaller.
