You can put this solution on YOUR website!
I guessing you meant
\n" ); document.write( " $\"+%28%28csc%5E2%28x%29%29-%28cot%5E2%28x%29%29%29%2F%28sec%5E2%28x%29%29\"$
\n" ); document.write( "with cot instead of cos. If I am wrong then you will have to re-post your question.

\n" ); document.write( "One of the Pythagorean identities is $\"cot%5E2%28x%29%2B1=csc%5E2%28x%29\"$ . Using this we can substitute in for $\"csc%5E2%28x%29\"$ :
\n" ); document.write( " $\"+%28%28cot%5E2%28x%29%2B1%29-%28cot%5E2%28x%29%29%29%2F%28sec%5E2%28x%29%29\"$
\n" ); document.write( "The cot's cancel:
\n" ); document.write( " $\"+1%2F%28sec%5E2%28x%29%29\"$
\n" ); document.write( "One of the Reciprocal identities is that sec and cos are reciprocals of each other. So:
\n" ); document.write( " $\"+1%2F%28sec%5E2%28x%29%29\"$
\n" ); document.write( "is equal to:
\n" ); document.write( " $\"cos%5E2%28x%29\"$
\n" ); document.write( " \n" ); document.write( "
