Ninul A. S. Tensor Trigonometry

In Geometry, division Planimetry includes metric part and trigonometry. In geometries of metric spaces from the end of XIX age their tensor forms are widely used. However the trigonometry is remained only in its scalar forms in a plane. The tensor trigonometry is development of the flat scalar trigonometry from Leonard Euler classic forms into general multi-dimensional tensor forms with vector and scalar orthoprojections and with step by step increasing... (Información más detallada)
