Question From Michael: what is 0.366 x cos square (02 degree 17 mins 27 seconds) |
Hi Michael,
One degree is 60 minutes and one second is 60 minutes which is $60 \times 60 = 3600$ degrees. Hence
\[0.2 \mbox{ degrees } 17 \mbox{ minutes } 27 \mbox{ seconds } = 0.2 + \frac{17}{60} + \frac{27}{3600} \mbox{ degrees.}\]
I hope this helps,
Penny
