Here's the plot:
\n" ); document.write( "
\n" ); document.write( "And here is a plot of \"+r+=+2%2Acos%28+theta+%29+\" :
\n" ); document.write( "\"+graph%28+400%2C400%2C+-4%2Api%2C+4%2Api%2C+-3%2C+3%2C+2%2Acos%28+x+%29+%29+\"
\n" ); document.write( "------------------------------------------------
\n" ); document.write( "Any cosine function must be symmetrical about the y-axis
\n" ); document.write( "and \"+cos%28+5%2Atheta+%29+\" is no different
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Start at \"+5%2Atheta+=+0+\" and rotate positive:
\n" ); document.write( "\"+5%2Atheta+\" - - - - - - - - \"+2%2Acos%28+5%2Atheta+%29+\"
\n" ); document.write( "----------------------------------------
\n" ); document.write( "0 - - - - - - - - - - - - - - 2
\n" ); document.write( "pi/2 - - - - - - - - - - - - 0
\n" ); document.write( "pi - - - - - - - - - - - - - -2
\n" ); document.write( "3pi/2 - - - - - - - - - - - - 0
\n" ); document.write( "2pi - - - - - - - - - - - - - 2
\n" ); document.write( "-----------------------------
\n" ); document.write( "And, if you rotate in the negative direction, you get
\n" ); document.write( "exactly the same result, so there is symmetry about
\n" ); document.write( "the y-axis\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
