Question 69

Multiple Choice

Find the indefinite integral. sin319θcos19θdθ\int \sin ^ { 3 } 19 \theta \sqrt { \cos 19 \theta } d \theta


A) 157(cos19θ) 32+1133(cos19θ) 72+C- \frac { 1 } { 57 } ( \cos 19 \theta ) ^ { \frac { 3 } { 2 } } + \frac { 1 } { 133 } ( \cos 19 \theta ) ^ { \frac { 7 } { 2 } } + C
B) sin419θ(cos19θ) 3276+C\frac { \sin ^ { 4 } 19 \theta ( \cos 19 \theta ) ^ { \frac { 3 } { 2 } } } { 76 } + C
C) 257(cos19θ) 322133(cos19θ) 72+C\frac { 2 } { 57 } ( \cos 19 \theta ) ^ { \frac { 3 } { 2 } } - \frac { 2 } { 133 } ( \cos 19 \theta ) ^ { \frac { 7 } { 2 } } + C
D) 257(cos19θ) 32+2133(cos19θ) 72+C- \frac { 2 } { 57 } ( \cos 19 \theta ) ^ { \frac { 3 } { 2 } } + \frac { 2 } { 133 } ( \cos 19 \theta ) ^ { \frac { 7 } { 2 } } + C
E) 457(cos19θ) 32457(cos19θ) 72+C\frac { 4 } { 57 } ( \cos 19 \theta ) ^ { \frac { 3 } { 2 } } - \frac { 4 } { 57 } ( \cos 19 \theta ) ^ { \frac { 7 } { 2 } } + C
