You can put this solution on YOUR website!
4 sin 2theta = 3 cos theta
\n" ); document.write( "-------------
\n" ); document.write( "If you mean
\n" ); document.write( "4sin(2theta) = 3cos(theta)
\n" ); document.write( "Use sin(2t) = 2sin(t)*cos(t)
\n" ); document.write( "---
\n" ); document.write( "8sin(t)cos(t) = 3cos(t)
\n" ); document.write( "8sin(t)cos(t) - 3cos(t) = 0
\n" ); document.write( "cos(t)*(8sin(t) - 3) = 0
\n" ); document.write( "cos(t) = 0
\n" ); document.write( "t = pi/2 + n*pi, n = any integer
\n" ); document.write( "=====================
\n" ); document.write( "8sin(t) - 3 = 0
\n" ); document.write( "sin(t) = 3/8
\n" ); document.write( "t = asin(3/8) + n*2pi
\n" ); document.write( "t = pi - asin(3/8) + 2n*pi\r
