Find csc(x) if cos= -3/4 and sin(x)<0
\n" ); document.write( "***
\n" ); document.write( "Reference angle in quadrant III where sin and cos <0.
\n" ); document.write( "sin(x)=-√(1-cos^(x))=-√(1-9/16)=-√(7/16)=-√7/4
\n" ); document.write( "csc(x)=1/sin(x)=-4/√7=-4√7/7 \n" ); document.write( "

\n" );
