For csc^2 a- 1/cotA cscA--what is the simplest equivalent trigonometric expression
\n" ); document.write( "HOPE YOU MEAN
\n" ); document.write( " (csc^2 a- 1)/cotA cscA
\n" ); document.write( "=COT^2(A)/COT(A)COSEC(A)=COT(A)/COSEC(A)=(COS(A)/SIN(A))/(1/SIN(A))=COS(A)
\n" ); document.write( "
\n" );
