You can put this solution on YOUR website!
cos(x)/(tan(x)+sec(x))
\n" ); document.write( "= cos/((sin/cos) + 1/cos)
\n" ); document.write( "= cos^2/(sin + 1)
\n" ); document.write( "= (1-sin^2)/(1+sin)
\n" ); document.write( "= (1-sin)*(1+sin)/(1+sin)
\n" ); document.write( "= 1 - sin(x)
\n" ); document.write( " \n" ); document.write( "
