how to use degress minutes and seconds with sin

there are 2 cases

a) your sin function can accept an input angle in degrees
b) your sin function must take an input angle in radians

a) All you have to do here is convert minutes and seconds to a decimal fraction of a degree. The formula is

Total_Degrees = Degrees + Minutes/60 + Seconds/3600

and you would use sin(Total_Degrees)

b) In this case you have to further convert Total_Degrees to radians and as there are 2*Pi radians in a 360 degree circle we have

Total_Radians = Total_Degrees * (Pi/180) radians

and you would use sin(Total_Radians)

Rom is absolutely right, if your calculator doesn't have a degrees minutes seconds button this is how you would have to do it.
But if your calc does have this button it is much easier

If you want to enter Sin(54 degrees, 16minutes and 20 seconds) into your calc

First you must check that your calc is in degrees mode. There will probably be a little D at the top of the display area.
just press
sin 54 'DMS' 16 'DMS' 20 'DMS' =
that's it.
Please note that the calc in the picture does not have this problem on it.
