Question

what is sin 26 degrees 20 seconds how to calculate this??

Answer 1

\[1 \text{ sec}=\frac{1}{60^2} \text{ deg}\]

Answer 2

so
\[20 \text{ sec }=\frac{20}{60^2} \text{ deg }\]

Answer 3

you can use your calculator to find sin(26+20/60^2 )
make sure you calculator is in deg mod

Answer 4

and for future reference:
\[1 \text{ min }=\frac{1}{60} \text{ deg}\]

Answer 5

we actually call these arc seconds and arc minutes
or I do
I think those are the universal terms

Answer 6

In case you are not sure why freckles did \(60^2\) there:

60 sec = 1 min
60 min = 1 degree

So in degrees, 1 second is one 60th of one 60th, or \(\dfrac{1}{60^2}\) of a degree.
