$\"sin%28a%2Bb%29=sin%28a%29cos%28b%29%2Bcos%28a%29sin%28b%29\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"sin%2818%29cos%2812%29%2Bcos%2818%29sin%2812%29=sin%2818%2B12%29\"$
\n" ); document.write( " $\"sin%2818%29cos%2812%29%2Bcos%2818%29sin%2812%29=sin%2830%29\"$
\n" ); document.write( " $\"sin%2818%29cos%2812%29%2Bcos%2818%29sin%2812%29=0.5\"$ \n" ); document.write( "
