A) cot3xcsc19xdx=119csc19x120csc20x+C\int \cot ^ { 3 } x \csc ^ { 19 } x d x = \frac { 1 } { 19 } \csc ^ { 19 } x - \frac { 1 } { 20 } \csc ^ { 20 } x + C
B) cot3xcsc19xdx=121csc21x119csc19x+C\int \cot ^ { 3 } x \csc ^ { 19 } x d x = \frac { 1 } { 21 } \csc ^ { 21 } x - \frac { 1 } { 19 } \csc ^ { 19 } x + C
C) cot3xcsc19xdx=121csc21x120csc20xx+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) cot3xcsc19xdx=120csc20x119csc19x+C\int \cot ^ { 3 } x \csc ^ { 19 } x d x = \frac { 1 } { 20 } \csc ^ { 20 } x - \frac { 1 } { 19 } \csc ^ { 19 } x + C
E) cot3xcsc19xdx=119csc19x121csc21x+C\int \cot ^ { 3 } x \csc ^ { 19 } x d x = \frac { 1 } { 19 } \csc ^ { 19 } x - \frac { 1 } { 21 } \csc ^ { 21 } x + C
