pi is 180 degrees
\n" ); document.write( ":
\n" ); document.write( "180 / 12 = 15 and -7 * 15 = -105
\n" ); document.write( ":
\n" ); document.write( "360 + (-105) = 255
\n" ); document.write( ":
\n" ); document.write( "255 is in the third quadrant where the sin is negative
\n" ); document.write( ":
\n" ); document.write( "sin(255) = −0.9659
