Let θ be an angle in quadrant IV such that cosθ= 4/9
\n" ); document.write( "Find the exact values of:
\n" ); document.write( "csc θ
\n" ); document.write( "cot θ
\n" ); document.write( "***
\n" ); document.write( "cos θ=4/9
\n" ); document.write( "sin θ=-√(1-cos^2θ)=-√(1-16/81)=-√(65/81)=-√65/9
\n" ); document.write( "csc θ=-1/sin θ=-9/√65=-9√65/65
\n" ); document.write( "cot θ=cos θ/sin θ=-4/√65=-4√65/65 \n" ); document.write( "

\n" );
