Step 11.33.2.3

Rewrite the expression.

$\frac{1}{2} \int {u_{3}}^{\frac{- 1}{2}} - {u_{3}}^{- 1} - {u_{3}}^{\frac{- 1}{1}} + 1 \cdot 1 {u_{3}}^{- \frac{3}{2}} d u_{3}$

Step 11.33.2.4

Divide $- 1$ by $1$ .

$\frac{1}{2} \int {u_{3}}^{\frac{- 1}{2}} - {u_{3}}^{- 1} - {u_{3}}^{- 1} + 1 \cdot 1 {u_{3}}^{- \frac{3}{2}} d u_{3}$

Step 11.34

Multiply $1$ by $1$ .

$\frac{1}{2} \int {u_{3}}^{\frac{- 1}{2}} - {u_{3}}^{- 1} - {u_{3}}^{- 1} + 1 {u_{3}}^{- \frac{3}{2}} d u_{3}$

Step 11.35

Multiply ${u_{3}}^{- \frac{3}{2}}$ by $1$ .

$\frac{1}{2} \int {u_{3}}^{\frac{- 1}{2}} - {u_{3}}^{- 1} - {u_{3}}^{- 1} + {u_{3}}^{- \frac{3}{2}} d u_{3}$

Step 11.36

Subtract ${u_{3}}^{- 1}$ from $- {u_{3}}^{- 1}$ .

$\frac{1}{2} \int {u_{3}}^{\frac{- 1}{2}} - 2 {u_{3}}^{- 1} + {u_{3}}^{- \frac{3}{2}} d u_{3}$

Step 11.37

Reorder ${u_{3}}^{\frac{- 1}{2}}$ and $- 2 {u_{3}}^{- 1}$ .

$\frac{1}{2} \int - 2 {u_{3}}^{- 1} + {u_{3}}^{\frac{- 1}{2}} + {u_{3}}^{- \frac{3}{2}} d u_{3}$

Step 12

Move the negative in front of the fraction.

$\frac{1}{2} \int - 2 {u_{3}}^{- 1} + {u_{3}}^{- \frac{1}{2}} + {u_{3}}^{- \frac{3}{2}} d u_{3}$

Step 13

Split the single integral into multiple integrals.

$\frac{1}{2} (\int - 2 {u_{3}}^{- 1} d u_{3} + \int {u_{3}}^{- \frac{1}{2}} d u_{3} + \int {u_{3}}^{- \frac{3}{2}} d u_{3})$

Step 14

Since $- 2$ is constant with respect to $u_{3}$ , move $- 2$ out of the integral.

$\frac{1}{2} (- 2 \int {u_{3}}^{- 1} d u_{3} + \int {u_{3}}^{- \frac{1}{2}} d u_{3} + \int {u_{3}}^{- \frac{3}{2}} d u_{3})$

Step 15

The integral of ${u_{3}}^{- 1}$ with respect to $u_{3}$ is $\ln (| u_{3} |)$ .

$\frac{1}{2} (- 2 (\ln (| u_{3} |) + C) + \int {u_{3}}^{- \frac{1}{2}} d u_{3} + \int {u_{3}}^{- \frac{3}{2}} d u_{3})$

Step 16

By the Power Rule, the integral of ${u_{3}}^{- \frac{1}{2}}$ with respect to $u_{3}$ is $2 {u_{3}}^{\frac{1}{2}}$ .

$\frac{1}{2} (- 2 (\ln (| u_{3} |) + C) + 2 {u_{3}}^{\frac{1}{2}} + C + \int {u_{3}}^{- \frac{3}{2}} d u_{3})$

Step 17

By the Power Rule, the integral of ${u_{3}}^{- \frac{3}{2}}$ with respect to $u_{3}$ is $- 2 {u_{3}}^{- \frac{1}{2}}$ .

$\frac{1}{2} (- 2 (\ln (| u_{3} |) + C) + 2 {u_{3}}^{\frac{1}{2}} + C - 2 {u_{3}}^{- \frac{1}{2}} + C)$

Step 18

Simplify.

$\frac{1}{2} (- 2 \ln (| u_{3} |) + 2 {u_{3}}^{\frac{1}{2}} - \frac{2}{{u_{3}}^{\frac{1}{2}}}) + C$

Step 19

Substitute back in for each integration substitution variable.
