I'm really lost here. It seems there is almost NO support of simple vectors in Mathematica v.3.0 If I want to add 2 vectors of which I have a polar (cylindrical) representation I am forced to do something like << Calculus`VectorAnalysis` SetCoordinates[Cylindrical] a={100, -115*Pi/180, 0} b={200, -30*Pi/180, 0} A=CoordinatesToCartesian[a, Cylindrical] B=CoordinatesToCartesian[b, Cylindrical] d=A+B D=CoordinatesFromCartesian[d, Cylindrical] and that is a HECK longer to do then by hand. There's got to be something simplier like: {100, -115*Pi/180, 0} + {200, -30*Pi/180, 0} or something... Also how do I find a magnitude of a vector. The Abs[] doesn't support this. Sqrt[d[[1]]^2+d[[2]]^2+d[[3]]^2] is simply hedious!!! Please help cause I'm really lost ;( Michael P.S. If possible, please also send a direct email to mmichael@idirect.com
