Chordate salient features, BSc, MSc Lecture by Ms. Priyanka khan.

This video is about the salient features of chordata. Presence of notochord, Dorsal tubular nerve cord and pharyngeal gill slits, post anal tail are the basic features of chordate, which should be present in any of the stages of life or throughout the lifetime. Ascidiaceae possess these characters in larval stage, branchiostoma throughout life time, …

Curvature and Torsion, B.Sc, M.Sc Lecture by Megha Sharma.

CURVATURE-The curvature vector at a point P of a given curve is the arc rate of rotation of tangent i.e. change in the direction of tangent as the point P moves along the curve and is equal to dt^/ds.the magnitude of curvature vector is called curvature of curve. TORSION- The Torsion vector at a point …

Fundamental Unit Vector and Fundamental Plane Lecture by Miss. Megha Sharma

The unit vector along tangent, principal normal, and binormal are denoted by t^,n^,b^ and form an orthogonal right handed triad so we can say that t^.n^ =0, n^.b^= 0, b^.t^ =0 & t^ ×n^ =b^ ,b^ ×t^ =n^, n^ ×b^ =t^. the set of unit vectors t^,n^,b^ which vary from point to point along a …
