(sin x/cos x)+(cos x/sin x)=
\n" ); document.write( "common denominator of cos x* sin x
\n" ); document.write( "numerator is sin^2 x+ cos^2 x
\n" ); document.write( "that equals 1
\n" ); document.write( "Therefore, we have 1/(cos x* sin x)=
\n" ); document.write( "1/ cos x * 1/ sin x
\n" ); document.write( "That is sec x* csc x \n" ); document.write( "

\n" );
