Find the value of x for which the statement csc(7x+9)=sec(5x) is true
\n" ); document.write( "csc(7x+9)=sec(5x)
\n" ); document.write( "1/sin(7x+9)=1/cos(5x)
\n" ); document.write( "Identity:cosA=sin(90-A)
\n" ); document.write( "1/sin(7x+9)=1/sin(90-5x)
\n" ); document.write( "7x+9=90-5x
\n" ); document.write( "7x+9+5x=90
\n" ); document.write( "12x=81
\n" ); document.write( "x=81/12=6.75
\n" ); document.write( "Note: This supersedes an earlier solution.
\n" ); document.write( "
\n" );
