Donvolution | How Sridhar Thinks

Let's consider the general problem of determining the volume $$v(K)$$ of the region where $$\sum f_i(x_i) < K$$; that is, of determining $$\int_{\sum f_i(x_i) < K} \prod dx_i$$. Let us define new variables $$y_i = f_i(x_i)$$; the problem is now expressed as $$\int_{\sum y_i…
