Tích phân hàm số toán cosecant

$\int \csc {ax}\,dx={\frac {1}{a}}\ln {\left|\csc {ax}-\cot {ax}\right|}+C$

$\int \csc ^{2}{x}\,dx=-\cot {x}+C$

$\int \csc ^{n}{ax}\,dx=-{\frac {\csc ^{n-1}{ax}\cos {ax}}{a(n-1)}}\,+\,{\frac {n-2}{n-1}}\int \csc ^{n-2}{ax}\,dx\qquad {\mbox{ (for }}n\neq 1{\mbox{)}}\,\!$
