$\frac{1}{2} \int - 6 {u_{3}}^{\frac{- 1}{2}} + 1 + 12 {u_{3}}^{- 1} - 8 {u_{3}}^{- \frac{3}{2}} d u_{3}$

Step 8.49

Step 12

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

$\frac{1}{2} (12 (\ln (| u_{3} |) + C) + \int - 6 {u_{3}}^{- \frac{1}{2}} d u_{3} + \int - 8 {u_{3}}^{- \frac{3}{2}} d u_{3} + \int d u_{3})$

Step 13

Since $- 6$ is constant with respect to $u_{3}$ , move $- 6$ out of the integral.

$\frac{1}{2} (12 (\ln (| u_{3} |) + C) - 6 \int {u_{3}}^{- \frac{1}{2}} d u_{3} + \int - 8 {u_{3}}^{- \frac{3}{2}} d u_{3} + \int d u_{3})$

Step 14

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

$\frac{1}{2} (12 (\ln (| u_{3} |) + C) - 6 (2 {u_{3}}^{\frac{1}{2}} + C) + \int - 8 {u_{3}}^{- \frac{3}{2}} d u_{3} + \int d u_{3})$

Step 15

Since $- 8$ is constant with respect to $u_{3}$ , move $- 8$ out of the integral.

$\frac{1}{2} (12 (\ln (| u_{3} |) + C) - 6 (2 {u_{3}}^{\frac{1}{2}} + C) - 8 \int {u_{3}}^{- \frac{3}{2}} d u_{3} + \int d u_{3})$

Step 16

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

$\frac{1}{2} (12 (\ln (| u_{3} |) + C) - 6 (2 {u_{3}}^{\frac{1}{2}} + C) - 8 (- 2 {u_{3}}^{- \frac{1}{2}} + C) + \int d u_{3})$

Step 17

Apply the constant rule.

$\frac{1}{2} (12 (\ln (| u_{3} |) + C) - 6 (2 {u_{3}}^{\frac{1}{2}} + C) - 8 (- 2 {u_{3}}^{- \frac{1}{2}} + C) + u_{3} + C)$
