You can put this solution on YOUR website!
Since all coterminal angles have the same trig values, we can subtract 2pi, so:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"cot+%2831pi%2F12%29+=+cot%287pi%2F12%29+=+1%2Ftan%287pi%2F12%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can compute $\"tan%287pi%2F12%29\"$ without using a calculator, using the addition formula

, and letting $\"alpha+=+pi%2F4\"$ , $\"beta+=+pi%2F3\"$ . You can then substitute those values in. I don't have enough time now, so I'll have you give it a try! Don't forget to invert your answer since you're looking for the cotangent, not the tangent. \n" ); document.write( "
