You can put this solution on YOUR website!
They are both true. By definition, $\"csc%28x%29=1%2Fsin%28x%29\"$ . If you solve for $\"sin%28x%29\"$ , you get $\"sin%28x%29=1%2Fcsc%28x%29\"$ \r

\n" ); document.write( "\n" ); document.write( "Similarly, $\"sec%28x%29=1%2Fcos%28x%29\"$ . Isolating $\"cos%28x%29\"$ gets you $\"cos%28x%29=1%2Fsec%28x%29\"$ \r
