You can put this solution on YOUR website!
factor out a cos(x) to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "cos^3(x) + cos(x) * sin^2(x) = cos(x) * (cos^2(x) + sin^2(x))\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since cos^2(x) + sin^2(x) = 1, this becomes cos(x) * 1 which becomes cos(x).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the expression can be simplified to cos(x).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
