Then … WebUsing the "partitioning the range of f" philosophy, the integral of a non-negative function f : R → R should be the sum over t of the areas between a thin horizontal strip between y = t and y = t + dt. This area is just μ{ x : f(x) &gt; t} dt. Let f ∗ (t) = μ{ x : f(x) &gt; t}. The Lebesgue integral of f is then defined by
