Here is my problem (C#) : double Y = 0.0; double X = -21.0; double q1_Test = Math.Atan2(0.0, -21.0); // gives Math.Pi double q1_Test2 = Math.Atan2(( double)Y, (double)X); // gives Math.Pi double w1 = <SomeclassInstanceGlobalHere>.getW1(); // This is a class which updates a variable double w2 = <SomeclassInstanceGlo...
