You can put this solution on YOUR website!
cotθ = 1/2, sin θ < 0 , sinθ = -2/√5 = -2√5 /5 , cosθ = -1/√5 =- √5/5
\n" ); document.write( "...........
\n" ); document.write( "sin (11π/6) = -1/2 , cos (11π/6) = √3 /2
\n" ); document.write( "..... Plug and Play     
\n" ); document.write( "sin(x - y) = sin x cosy - cos x sin y
\n" ); document.write( "sin(θ − 11π/6) =
\n" ); document.write( ".......
\n" ); document.write( "tan 2θ = 2tanx / (1-tan^2x) = 4/(1-4) = -4/3
\n" ); document.write( "tan ( 3π/2) = cos/sin = 0
\n" ); document.write( ".........Plug and Play
\n" ); document.write( "tan(x + y) = tan x + tan y)/(1- tan x tan y
\n" ); document.write( "tan(2θ + 3π/2) = -4/3
