    Post Determine the Degrees

    For the math real men:

    Suppose a bone, experiencing 3 directional forces, in return the dog on the left goes at 20 newtons, at right goes 40 newtons, at top 20 newtons

    (-20,0)
    (0,20)
    (40,0)

    r=20,20

    Do you know what the degrees it is? How much Newtons it is?

    You want a force vector, yes? That'll be 45 degrees, sqr(800) Newtons. About 28 Newtons.

    Using euler transformation
    x+yi=sqr(x^2+y^2)e^atn(x/y)i
    phi=atn(x/y)
    arcus tangens on calculators and in vb screws up on y=0 and can't handle the two other quadrants, in C++ you can use atan2
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
