You can put this solution on YOUR website!
(cscO + cotO)(cscO - cotO) = 1
\n" ); document.write( "----
\n" ); document.write( "You have the form: (a+b)(a-b) = a^2-b^2
\n" ); document.write( "-------
\n" ); document.write( "(csc^2 - cot^2) = 1
\n" ); document.write( "-----
\n" ); document.write( "((1/sin^2) - (cos^2/sin^2) = 1
\n" ); document.write( "----
\n" ); document.write( "(1-cos^2)/sin^2 = 1
\n" ); document.write( "-----
\n" ); document.write( "sin^2/sin^2 = 1
\n" ); document.write( "----
\n" ); document.write( "1 = 1
\n" ); document.write( "=============
