Why is the Riemann/Darboux Integral still taught in undergrad analysis classes? The lebesgue integral is much more useful and is only slightly more complicated when first learning it.

Afterwards it is actually easier.

I will start.


Use the Mayer-Vietoris sequence, [math]\ldots \to {H^i}\left( {X,\mathcal{F}} \right) \to {H^i}\left( {U,\mathcal{F}} \right) \oplus {H^i}\left( {V,\mathcal{F}} \right) \to {H^i}\left( {U \cap V,\mathcal{F}} \right) \to {H^{i + 1}}\left( {X,\mathcal{F}} \right) \to \ldots [/math], to prove that [math]{H^1}\left( {{S^1},{A_{{S^1}}}} \right) \cong A[/math] for any abelian group [math]A[/math].
