Need to calculate topography's projections using azimute!

I'm assuming that you mean degrees, minutes, seconds:

There are 60 minutes in each degree and 60 seconds in each minute (making 3600 seconds in one degree).

sin( 351° 22' 58" )  =  sin( 351 + 22/60 + 58/3600 )  =  sin( 351.3827777...)  =  - 0.14983...

If that's not what you mean ????
