question 364

Multiple Choice

Find the derivative.
- $s = t ^ { 6 } \cos t - 8 t \sin t - 8 \cos t$

• A) \(\frac { d s } { d t } = - t ^ { 6 } \sin t + 6 t ^ { 5 } \cos t - 8 t \cos t - 16 \sin t\)
• B) \(\frac { d s } { d t } = - t ^ { 6 } \sin t + 6 t ^ { 5 } \cos t - 8 t \cos t\)
• C) \(\frac { d s } { d t } = - 6 t ^ { 5 } \sin t - 8 \cos t + 8 \sin t\)
• D) \(\frac { d s } { d t } = t ^ { 6 } \sin t - 6 t ^ { 5 } \cos t + 8 t \cos t\)
