question 51

Multiple Choice

Find the derivative of the function. $f ( \theta ) = \frac { 3 } { 7 } \sin ^ { 2 } 3 \theta$

• A) \(f ^ { \prime } ( \theta ) = \frac { 3 \sin 3 \theta \cos 3 \theta } { 7 }\)
• B) \(f ^ { \prime } ( \theta ) = \frac { 18 \sin 3 \theta \cos 3 \theta } { 7 }\)
• C) \(f ^ { \prime } ( \theta ) = \frac { 18 \cos 3 \theta } { 7 }\)
• D) \(f ^ { \prime } ( \theta ) = - \frac { 18 \sin 3 \theta \cos 3 \theta } { 7 }\)
• E) \(f ^ { \prime } ( \theta ) = \frac { 18 \sin 3 \theta } { 7 }\)
