You can put this solution on YOUR website!
Since I can not show a theta symbol, let X = theta\r
\n" ); document.write( "\n" ); document.write( "Given: $\"Cos%28X%29+=+Sin%28X%29%2ACot%28X%29\"$
\n" ); document.write( "You need to know that $\"Cot%28X%29+=+%28Cos%28X%29%29%2F%28Sin%28X%29%29\"$
\n" ); document.write( "Then rewrite the equation
\n" ); document.write( " $\"Cos%28X%29+=+Sin%28X%29%2A%28Cos%28X%29%29%2F%28Sin%28X%29%29\"$ The Sin(X)'s cancel out
\n" ); document.write( " $\"Cos%28X%29+=+cross%28Sin%28X%29%29%2A%28Cos%28X%29%29%2Fcross%28%28Sin%28X%29%29%29\"$
