Find all values of t in the interval [0, 2π] satisfying the given equation
\n" ); document.write( "4 sin 2t + 2 tan 2t = 0
\n" ); document.write( "divide by 2
\n" ); document.write( "2sin2t+tan2t=0
\n" ); document.write( "2sin2t+sin2t/cos2t=0
\n" ); document.write( "sin2t(2+(1/cos2t))=0
\n" ); document.write( "..
\n" ); document.write( "sin2t=0
\n" ); document.write( "2t=0
\n" ); document.write( "t=0
\n" ); document.write( "or
\n" ); document.write( "2+(1/cos2t)=0
\n" ); document.write( "1/cos2t=-2
\n" ); document.write( "cos2t=-1/2
\n" ); document.write( "2t=2π/3, 4π/3 (In Q2 and Q3 in which cos<0)
\n" ); document.write( "t=π/3, 2π/3
\n" ); document.write( "
\n" );
