My answer to a deleted question Interpretation of exponentation and permutation on math.SE

WayneXMayersX asked this question.

Question

I have $3^3$, can I call it a permutation/permutation with repetition?

Nvec = 10000:10000:1000000;  % no of intervals
rrsumvec = zeros(size(Nvec));
for ind = 1:length(Nvec)
    N = Nvec(ind);
    dx = 5 / N;
    x = (1:N) * dx;
    fx = sqrt(25 - x.^2);
    rrsum(ind) = sum(fx * dx);
end

# input
a = int(input("Donner la valeur de a: "))
b = int(input("Donner la valeur de b: "))

# avant échange
print("a = ",a)
print("b = ",b)

# échange 
a, b = b, a
