You can put this solution on YOUR website!
$\"sin%5E2%28x%29%2B+cos%28x%29+%2B1+=0\"$
\n" ); document.write( " $\"%281-cos%5E2%28x%29%29%2B+cos%28x%29+%2B1+=0\"$
\n" ); document.write( " $\"-cos%5E2%28x%29%2Bcos%28x%29%2B2=0\"$
\n" ); document.write( " $\"cos%5E2%28x%29-cos%28x%29-2=0\"$
\n" ); document.write( " $\"u%5E2-u-2=0\"$
\n" ); document.write( " $\"%28u-2%29%28u%2B1%29=0\"$
\n" ); document.write( "Two possible solutions:
\n" ); document.write( " $\"u-2=0\"$
\n" ); document.write( " $\"u=2\"$
\n" ); document.write( " $\"cos%28x%29=2\"$
\n" ); document.write( "No solution here.
\n" ); document.write( " $\"u%2B1=0\"$
\n" ); document.write( " $\"u=-1\"$
\n" ); document.write( " $\"cos%28x%29=-1\"$
\n" ); document.write( " $\"x=pi\"$
\n" ); document.write( "However since your solution has to lie with [ $\"0\"$ , $\"2\"$ ], there is no solution.
