41. A unit vector tangent to the path pointing in the direction of motion at the chosen moment in time. 42. The unit circle on the left shows the rotation of the unit vectors with " s ". 43. This is impossible because " z " is the norm limit of a sequence of unit vectors . 44. G _ n ( x ) represents a unit vector that is perpendicular to the previous curve at x. 45. Either has a weakly Cauchy subsequence, or it admits a subsequence equivalent to the standard unit vector basis of. 46. In vector notation, a hat above a letter indicates a unit vector ( a dimensionless magnitude of 1 ). 47. The slash operation maps the unit vectors of, or any 4-dimensional vector space, to basis vectors. 48. I would like to know how complex does calculating the cosine between two unit vectors become as dimensions are added. 49. :: : : : A pure state is just another name for a unit vector in the Hilbert space. 50. Since the coordinate system is moving, the time derivative of the unit vector , er, is not zero.
