You still have whatever if you add zero to it. So what is the sine of a 180 degree straight angle.
the way that you would work it out is..
sin(180+0)= sin(180)cos(0)+ cos(180)sin(0) which gives you the same answer as sin(180)
sin(180+0)= sin(180)cos(0)+ cos(180)sin(0) which gives you the same answer as sin(180)
