PG TRB MATHS | DIFFERENTIAL GEOMETRY |

in this video we are going to learn Important Theorems And Results in differentia geometry...these are all asked in previous years pg trb maths exams..gaussian curvature,normal curvature,first fundamental forms,dupins indicatrix,natural equations of a curve,

19th point may be wrong, ruled surface means generated by one parameter family of st lines, developable means one parameter family of planes .

[johncirani]

Very clear explanation sir, but I problems pls send extra videos like this for unit wise ...if u send full covered syllabus for unit wise it will be so helpful to us.

[rkalpana]

Thank you very useful. but not covered full unit this video. possible means send it full unit.

The radius of spherical curvature R is


A) ρ2+σ2ρ′2

B) (ρ2+σ2ρ′2)1/2

C) (ρ2+σ2σ′2)2

D) ρ2−σ2ρ′2. Here answer. A or B
Because. R^2=p^2+sigma^2p'^2
