### Integration by Substitution Exercises Answers

These are textbook answers. Some answers not given here may be in the worked problems (but results are not guaranteed).

#### Hints

• C98-9. {$\displaystyle u=3x +2$}
• C98-12. {$\displaystyle u=4 + x^2$}
• C98-14. {$\displaystyle u= \cos x$}

• C98-9. {$\displaystyle {2\over 9}(3x+2)^{3 \over 2}+ C$}
• C98-10. {$\displaystyle \ln\sqrt[3]{3x+2}+ C$}
• C98-11. {$\displaystyle {1\over 3}\arctan({3x+2})+ C$}
• C98-12. {$\displaystyle {1 \over 3}(4+x^2)^{3\over 2}+ C$}
• C98-13. {$\displaystyle \ln \sqrt{4+x^2} + C$}
• C98-14. {$\displaystyle -{2 \over 3}(\cos x)^{3 \over 2} + C$}
• C98-15. {$\displaystyle {2 \over 3}(\sin x)^{3 \over 2} + C$}
• C98-16. {$\displaystyle \sin x + 2\sin^2x + 3\sin^3x +C$}
• C98-17. {$\displaystyle -\cos x + {{(\cos^3 x)} \over 3}$}

This is a student's notebook. I am not responsible if you copy it for homework, and it turns out to be wrong.

Figures are often enhanced by hand editing; the same results may not be achieved with source sites and source apps.
