Hi,

I want to evalute in degrees.

 

restart:with(Units[Natural]):

sin(45 * deg);  # it works

 

>alpha[1]:=4.25 * deg;
> theta[1]:=11.31 *deg;
> theta[2]:=78.69 *deg;
> alpha[2]:=-9.25 *deg;
> a:=1400.00;  #  a and b should be real values
> b:=509.90;

>-b*sin(alpha[2]+alpha[1]-beta[1]-theta[2])+b*sin(beta[1]-theta[2]):

Error, (in Units:-Standard:-+) the units `arcdeg` and `1` have incompatible dimensions

not working...
