Geometric Construction of the Geometric Series
Peer reviewed Peer reviewed
Maor, Eli – International Journal of Mathematical Education in Science and Technology, 1977
A geometric method for constructing one infinite geometric series is described. The unit of the sum of the series is analyzed, and the behavior of the sum near two points is studied. (DT)

On the Addition of Planar Rotations
Peer reviewed Peer reviewed
Maor, Eli – International Journal of Mathematical Education in Science and Technology, 1974
An interpretation of the transformation formulas for rotations in a plane in terms of the exponential function is given. Addition of two rotations is shown to correspond to the multiplication of the two corresponding matrices. (Author/LS)
