You can put this solution on YOUR website!
cot^2x-1; solve in terms of sinx
\n" ); document.write( "------------
\n" ); document.write( "cot^2x-1
\n" ); document.write( "It's not an equation, so there's nothing to solve.
\n" ); document.write( "If you want to write it in terms of sine:
\n" ); document.write( "cot^2x-1 = cos^2/sin^2 - 1
\n" ); document.write( "= $\"%281+-+sin%5E2%28x%29%29%2Fsin%5E2%28x%29+-+1\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
