1. sec^2x-2=0
\n" ); document.write( "sec(x) = sqrt(2)
\n" ); document.write( "x = 45 degrees or pi/4
\n" ); document.write( "---------------------------------
\n" ); document.write( "2. csc6x+2=0
\n" ); document.write( "csc(6x) = -2
\n" ); document.write( "6x = 210 degrees or (7/6)pi
\n" ); document.write( "x = 36 degrees or (7/12)pi
\n" ); document.write( "---------------------------------
\n" ); document.write( "3. 4sinxcosx+2sinx+2cosx+1 = 0
\n" ); document.write( "---------------------------------
\n" ); document.write( "
\n" ); document.write( "4. 2cosx-sqrt(2)=0
\n" ); document.write( "cos(x) = sqrt(2)/2
\n" ); document.write( "x = 45 degrees or pi/4
\n" ); document.write( "=======================
