Simplify the following, where k represents any integer.
\n" ); document.write( "cos(2kpi-theta)(-sin(2kpi-theta))
\n" ); document.write( "= cos(-theta)*(-sin(-theta))
\n" ); document.write( "---
\n" ); document.write( "= cos(theta) * sin(theta)
\n" ); document.write( "----
\n" ); document.write( "= (1/2)sin(2*theta)
\n" ); document.write( "============================
