Curvature for Curves and Surfaces
Curves and surfaces in space
Most of high school mathematics is concerned with straight lines and planes. There is of course far more to geometry than these flat objects. Classically differential geometry is concerned with how curves and surfaces bend and twist in space. The word “curvature” is used to denote the various measures of twisting that have been discovered.
Unfortunately, the calculations and formulas to compute the different types of curvature ...
