Geometry and forming of the normal surfaceswith system of plane coordinate lines
The surfaces with system of coordinate lines lying in normal plane of some directrix are investigated. The vector equation of the surfaces and the formulas of the main quadratic forms are received. The drawings of surfaces made in MathCad system with different directrix and genetrix lines are shown
