Question: Given I = a b f ( x ) dx Assume, Ln and Rn are the left and right reimann sums respectively that both estimate
Given
I=abf(x) dx
Assume, Ln and Rn are the left and right reimann sums respectively that both estimate I
Which are true
1) If f>0 and f'<0 on [a,b] then Ln < I
2) If f>0 and f'<0 on [a,b] then Ln < I
3) If f<0 and f'>0 on [a,b] then Rn < I
4) If f<0 and f'>0 on [a,b] then Rn > I
