• A) \(\int \cot ^ { 3 } x \csc ^ { 19 } x d x = \frac { 1 } { 19 } \csc ^ { 19 } x - \frac { 1 } { 20 } \csc ^ { 20 } x + C\)
• B) \(\int \cot ^ { 3 } x \csc ^ { 19 } x d x = \frac { 1 } { 21 } \csc ^ { 21 } x - \frac { 1 } { 19 } \csc ^ { 19 } x + C\)
• C) \(\int \cot ^ { 3 } x \csc ^ { 19 } x d x = \frac { 1 } { 21 } \csc ^ { 21 } x - \frac { 1 } { 20 } \csc ^ { 20 x } x + C\)
• D) \(\int \cot ^ { 3 } x \csc ^ { 19 } x d x = \frac { 1 } { 20 } \csc ^ { 20 } x - \frac { 1 } { 19 } \csc ^ { 19 } x + C\)
• E) \(\int \cot ^ { 3 } x \csc ^ { 19 } x d x = \frac { 1 } { 19 } \csc ^ { 19 } x - \frac { 1 } { 21 } \csc ^ { 21 } x + C\)
