A class for multidimensional vectors, with arithmetic, and rotation.

Classes
		Vector Vector2D   class Vector     A class that implements vectors as ordered tuples in any (integral) dimension.   Note that Vector(3) returns (0, 0, 0), but Vector(3, 3) returns (3, 3).     Methods defined here: Distance(self, other) MaxDistance(self, other) Rotate(self, xAngle, vPerp) __add__(self, other) __div__(self, xDiv) __init__(self, *tp) __len__(self) __mul__(self, xMul) __neg__(self) __repr__(self) __rmul__(self, xMul) __str__(self) __sub__(self, other) copy(self) dot(self, other) length(self) list(self) max(self, other) min(self, other) tuple(self)   class Vector2D(Vector)       Methods defined here: Perpendicular(self) Rotate(self, xAngle) Toward(self, other) __init__(self, tp) Methods inherited from Vector: Distance(self, other) MaxDistance(self, other) __add__(self, other) __div__(self, xDiv) __len__(self) __mul__(self, xMul) __neg__(self) __repr__(self) __rmul__(self, xMul) __str__(self) __sub__(self, other) copy(self) dot(self, other) length(self) list(self) max(self, other) min(self, other) tuple(self)

Functions
		atan2(...) atan2(y, x)   Return the arc tangent (measured in radians) of y/x. Unlike atan(y/x), the signs of both x and y are considered. cos(...) cos(x)   Return the cosine of x (measured in radians). sin(...) sin(x)   Return the sine of x (measured in radians). sqrt(...) sqrt(x)   Return the square root of x.
