Hi, I was always wondering why ArcTan[] alow one and two arguments, i.e., ArcTan[x] and ArcTan[x,y] (x, and y in *that* order) Regards Jens TL wrote: > Is there a function in Mathematica that would return the azimuth between > two points with known coordinates, 0 being North? > For example having A(0,0), B(1,0) - the azimuth should be 90 degrees > its like ArcTan[dx/dy], but I need the quadrant taken into account as > well and I need it to handle 90 and 270 degrees properly too > > /it doesn't need to convert the angles to degrees, rads is ok/ >
