Hi there, \n" ); document.write( "You have not listed limits \n" ); document.write( "so I am working this out \n" ); document.write( "for 0<=θ=<2π \n" ); document.write( "2 sin(3θ) + 1 = 0 \n" ); document.write( "2 sin(3θ) = -1 \n" ); document.write( "sin(3θ) = -1/2 \n" ); document.write( "(3θ) = π/6, 5π/6 \n" ); document.write( "Because you have (3θ) you must \n" ); document.write( "add 2π to each of your values twice:- \n" ); document.write( "(3θ) = π/6, 5π/6,13π/6,17π/6 \n" ); document.write( "25π/6 and 29π/6. \n" ); document.write( "Now you divide all the values by 3. \n" ); document.write( "π = π/18, 5π/18,13π/18,17π/18 \n" ); document.write( "25π/18 and 29π/18. \n" ); document.write( "Hope this helps :-) \n" ); document.write( " |
