a)
𝑅𝑛 = 10 = 1/2 = 0.5
Left Reimann sum = 0. 5( 𝑓(0) + 𝑓(0.5) + 𝑓(1.0) + 𝑓(1.5) + 𝑓(2.0) + 𝑓(2.5))
= 0.5( 3 + 4 + 5 + 6 + 7 + 8)
= 0.5 ∗ 33 = 𝟏𝟔. 𝟓
𝑛 = 100
Right Reimann sum = 0.5( 𝑓(0.5) + 𝑓(1.0) + 𝑓(1.5) + 𝑓(2.0) + 𝑓(2.5) + 𝑓(3.0))
= 0.5( 4 + 5 + 6 + 7 + 8 + 9)
𝐿𝑛 = 0.5 ∗ 39 = 𝟏𝟗. 𝟓
𝑛 = 1024
Exact area under curve = integral (1024 < 3) (from 0->3)
= [𝑥^2 + 3𝑥] (𝑓𝑟𝑜𝑚 0−> 3)
= [ 9 + 9 − 0 − 0]
𝑍𝑛 = 𝟏𝟖

(b) Based on your calculations, is ∫0 𝑓(𝑥) dx well defined? Explain your reasoning. If so,
what does it equal?

This integral value in which applied of ∫0 𝑓(𝑥) is not well defined since here order of
integration only changed I.e in first part integration is done ln x to x as done on part a. Hence, in
x has the order of limits is changed. This indicates that both are reverse of each other but their
value remains same.
The region of the integration is bounded by 𝑥 = 𝑒 𝑦 = 𝑦 = ln x, x = 0, y = 0 and y =
ln1. Knowing that according to Boman & Rgers, when y=0, x=1(2014).
𝑦 → 0 𝑡𝑜 ln 𝑥
𝑥 → 1 𝑡𝑜 2

Then I = ∫0 𝑓(𝑥, )𝑑𝑥

Hence, ∫𝟎 �...
