Like in the univariate case, you can think of the argument of the exponential function as being a downward opening quadratic bowl. The coefficient in front (i.e., 1 (2π)n/2|Σ|1/2) has an even more complicated form than in the univariate case. However, it still does not dependConsider the statement \[\forall x\in\mathbb{R}\, (x^2\geq0). \nonumber\] By direct calculations, one may demonstrate that \(x^2\geq0\) is true for many \(x\)-values. But it does not prove that it is true for every \(x\), because there …
