In this problem you will calculate the area between
f(x) = 6 x and the x -axis over the interval \lbrack 0, 3 \rbrack
using a limit of right-endpoint Riemann sums:

Express the following quantities in terms of

- We start by subdividing
\lbrack 0, 3 \rbrack inton equal width subintervals\lbrack x_0, x_1 \rbrack, \lbrack x_1, x_2 \rbrack, \ldots, \lbrack x_{n-1}, x_{n} \rbrack each of width\Delta x . Express the width of each subinterval\Delta x in terms of the number of subintervalsn .

\Delta x =

x_1, x_2, x_3 = (Enter a comma separated list.)

- Find a general expression for the right endpoint
x_k of thek ^{th}subinterval\lbrack x_{k-1}, x_{k} \rbrack , where1 \leq k \leq n . Express your answer in terms ofk andn .
