The reason for the (RR) term is to make the equation "solvable" for "R" and to have "R" in the menu following the angle (the variables appear in the order "Angle", "R", "X", "Y"). If I do not insert (RR), the solver beeps and says that he cannot find a solution for "R" (but it shows the corect result for R)  with (RR) it stays silent and directly shows the result for R. Again, there may be better ways to achieve this. [I also learned that there is an angle symbol "∡" in the character set, so I replaced the nordic Ø with that symbol)] Martin
