I am trying to determine the determinant of the following uniformly distributed random symmetric matrix $A$ with zero mean and $approx 2.9$ standard deviation.
begin{equation}
A=
begin{pmatrix}
1 & cos alpha_{12} & cos alpha_{13} & dots &cos alpha_{1N} \
cos alpha_{12}& 1 & cos alpha_{23} & dots &cos alpha_{2N} \
cos alpha_{13} & cos alpha_{23} & 1 & dots &cos alpha_{3N} \
vdots & vdots & vdots & quad & vdots \
cos alpha_{1N} & cos alpha_{2N} & cos alpha_{3N} & dots & 1\
end{pmatrix}
end{equation}
Where each vectors are linearly independent and $alpha_{ij} in [-0.5,0.5]$, for all $i,j=1,2,3,dots,N$.
Any valuable resource or help is appreciated.

Welcome to MSE. It will be more likely that you will get an answer if you show us that you made an effort. This should be added to the question rather than in the comments.

You wrote symmetric matrix. Thus we should assume $alpha_{ij}=alpha_{ji}$.

If you're talking about a random matrix you should specify the probability distribution for the parameters $alpha_{ij}$.
