You can put this solution on YOUR website!
We want to show that $\"tan%28x%29csc%28x%29+=+sec%28x%29\"$ . Rewriting everything in terms of sin and cos,\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%28sin%28x%29%2Fcos%28x%29%29%281%2Fsin%28x%29%29+=+1%2Fcos%28x%29\"$ Cancel out sin(x) to obtain\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"1%2Fcos%28x%29+=+1%2Fcos%28x%29\"$ which is true for all x that makes the values defined. \n" ); document.write( "
