(L-8) MAT-309/233709 : Differential Geometry_Spherical Indicatrices-4, Zahangir Alam, Asstt. Prof.

Lecture-08 : Date-08 Aug 2020 Time-11:45 AM
For 3rd Year B.Sc. (Hon’s), Mathematics Students
Course Name : Differential Geometry [233709 (Old), MAT-309 (New)]
Chapter : Spherical Indicatrices [Part-4]

In the chapter #Spherical_Indicatrices of Differential Geometry, Students will learn what is #Spherical_Indicatrix and three types of Spherical indicatrices : Spherical indicatrix of the #tangent, #normal and #binormal. They also determine curvature and torsion of these Spherical indicatrices and what are #Involutes and #Evolutes; Involutes and its equation; Evolutes and its equation; Curvature and torsion of the evolute; what are #Bertrand_Curves, #Cross_Ratio and #Mannheim's_theorem. Hope Students will be benefited to see these lectures on Spherical Indicatrices.
