"WebRemember that the general term in the Riemann summation is f ( a + i ⋅ b − a n) ⋅ b − a n (since we use "right-endpoint rule" in constructing these limits). We see that b − a = 1 , but we don't see any "a" term in the "function factor". So it must be that a = 0 and the rest of the definite integral expression follows from there.
