Chapter 13: Q. 26 (page 1055)

Evaluate the iterated integral :
${鈭�}_{1}^{3} 鈥� {鈭�}_{鈭� 1}^{5} 鈥� {鈭�}_{0}^{3} 鈥� x y^{2} z d z d y d x$

Short Answer

Expert verified

$\frac{189}{2}$

Step by step solution

Step 1. Given information.

Given integral is :

${鈭�}_{1}^{3} 鈥� {鈭�}_{鈭� 1}^{5} 鈥� {鈭�}_{0}^{3} 鈥� x y^{2} z d z d y d x$

We have to evaluate it.

Step 2. Evaluate.

Given ${鈭�}_{1}^{3} 鈥� {鈭�}_{鈭� 1}^{5} 鈥� {鈭�}_{0}^{3} 鈥� x y^{2} z d z d y d x$

$\begin{aligned} = {鈭�}_{1}^{3} 鈥� {鈭�}_{鈭� 1}^{5} 鈥� ({鈭�}_{0}^{3} 鈥� x y^{2} z d z) d y d x \\ = {鈭�}_{1}^{3} 鈥� {鈭�}_{鈭� 1}^{5} 鈥� (x y^{2} {鈭�}_{0}^{3} 鈥� z d z) d y d x \\ = {鈭�}_{1}^{3} 鈥� {鈭�}_{鈭� 1}^{5} 鈥� (x y^{2} {(\frac{z^{2}}{2})}_{0}^{3}) d y d x \\ = {鈭�}_{1}^{3} 鈥� {鈭�}_{鈭� 1}^{5} 鈥� (x y^{2} (\frac{9}{2})) d y d x \end{aligned}$

Step 3. Integrate with respect to y.

$\begin{aligned} = {鈭�}_{1}^{3} 鈥� (\frac{9}{2} x {鈭�}_{鈭� 1}^{5} 鈥� y^{2} d y) d x \\ = {鈭�}_{1}^{3} 鈥� (\frac{9}{2} x {(\frac{y^{3}}{3})}_{鈭� 1}^{5} d x \\ = {鈭�}_{1}^{3} 鈥� (\frac{9}{2} x (\frac{5^{3}}{3} 鈭� \frac{(鈭� 1)^{3}}{3}) d x \\ = {鈭�}_{1}^{3} 鈥� (\frac{9}{2} x (42)) d x \\ = {鈭�}_{1}^{2} 鈥� 189 x d x \end{aligned}$

Integrate with respect to x.

$\begin{aligned} = 189 {鈭�}_{0}^{1} 鈥� x d x \\ = 189 {(\frac{x^{2}}{2})}_{0}^{1} \\ = 189 (\frac{1}{2} 鈭� 0) \\ = \frac{189}{2} \end{aligned}$
