Prove(cosecx)/(cotx+tanx) =cosx
\n" ); document.write( "..
\n" ); document.write( "(cosecx)/(cotx+tanx) =cosx
\n" ); document.write( "start with left side
\n" ); document.write( "(1/sin)/[(cos/sin)+(sin/cos)]
\n" ); document.write( "(1/sin)/[(cos^2+sin^2)/(sincos)]
\n" ); document.write( "(1/sin)/[1/(sincos)]
\n" ); document.write( "sincos/sin=cos
\n" ); document.write( "verified: left side=right side \n" ); document.write( "

\n" );
