%0 Journal Article %T Rotations in three, four, and five dimensions %A Jason Hanson %J Mathematics %D 2011 %I arXiv %X The geometry of rotations in dimensions 3, 4, and 5 is discussed using the matrix exponential map. Explicit closed formulas for the exponential of an antisymmetric matrix, as well as the logarithm of a rotation, are given for these dimensions. %U http://arxiv.org/abs/1103.5263v1
