An example of this rigidity and path dependence is âour old friendâ <math>logz</math>. There is no power series expansion about the origin due to the singularity there but depending on the path chosen of points around the origin (clockwise or anti-clockwise) the function extends or subtracts in value by <math>2Ďi</math>. See chapter 5 and the euler formula (<math>e^{Ďi}=-1</math>) for a refresher. | An example of this rigidity and path dependence is âour old friendâ <math>logz</math>. There is no power series expansion about the origin due to the singularity there but depending on the path chosen of points around the origin (clockwise or anti-clockwise) the function extends or subtracts in value by <math>2Ďi</math>. See chapter 5 and the euler formula (<math>e^{Ďi}=-1</math>) for a refresher. | ||
