Use The Left And Right Riemann Sums With 4 Rectangles To Estimate The Signed Area Under The Curve Of Yx13 On The Interval Of 36 Round Your Answers To The Second class=

Answer :

Solution:

Given:

[tex]\begin{gathered} y=\sqrt[3]{x-1} \\ on\text{ the interval \lbrack3,6\rbrack} \end{gathered}[/tex]

where a = 3, b = 6, n = 4.

This gives

[tex]\triangle\text{x=}\frac{6-3}{4}=\frac{3}{4}[/tex]

Divide the interval into 4 subintervals of the length Δx with the following endpoints:

[tex]a=3,\text{ }\frac{15}{4},\frac{9}{2},\frac{21}{4},6=b[/tex]

For the Left Riemann sum, we evaluate the function at the left endpoints of the subintervals. Thus, we have

sum up the values and multiply by Δx, we have

[tex]4.349280826349355[/tex]

To the second decimal place, we have the Left Riemann sum to be

[tex]4.35[/tex]

For the Right Riemann sum, we evaluate the function at the right endpoints of the subintervals. Thus, we have

sum up the values and multiply by Δx, we have

[tex]4.686821998935723[/tex]

To the second decimal place, we have the Right Riemann sum to be

[tex]4.69[/tex]
