\n" ); document.write( "Factor:
\n" ); document.write( "sec(2theta)[sec(2theta+1] = 0
\n" ); document.write( "---
\n" ); document.write( "sec(2theta) = 0 or sec(2theta) = -1
\n" ); document.write( "---
\n" ); document.write( "There is no solution for sec(2theta) = 0
\n" ); document.write( "---
\n" ); document.write( "If sec(2theta) = -1, 2theta = pi, and theta = pi/2
