tg^2(29) = tg^2(29*pi/180) = 0.307
tg^2(61) = ctg^2(29*pi/180) = 3.255
tg^2(54) = 1 + 2/ \sqrt{5} = 1.894
tg^2(36) = 5 - 2 \sqrt{5} = 0.528

The day of my journey to Geneva was very foggy
and I was afraid about the flight might be cancelled.
When I rang the airport, they told me I should be check
In at the normal time. On the way to there in a taxi the
Fog seemed to be getting thicker but as we arrived I saw
a plane landing, which it cheered me up. There were
a lot of people in the departure lounge at the first but
more and more of them disappeared as their flights
were called. After an hour in there were only about six
of us left and then we had heard the words I'd been
dreading: 'We are regret to announce the cancellation
of Flight 267 to Geneva. 'Naturally, we all demanded
to know if what was going to happen to us and, in the
end, the airline out us on a plane to Dublin. From there
we were caught a flight to Paris, where we had to travel
to a different terminal by the bus before finally boarding
a plane for Geneva. We arrived, exhausted, five hours late.
