## anonymous one year ago what is sin 26 degrees 20 seconds how to calculate this??

1. freckles

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

2. freckles

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

3. freckles

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

4. freckles

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

5. freckles

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

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.
