#53: Three Dimensional Geometry (Video 4 of 9)

By Mahesh Mehta Sir | Class - 10+2

Topic Covered:-
1. Cartesian Equation of a line using two points form (x - x_1 )/(x_2 - x_1 )= (y - y_1 )/(y_2 - y_1)= (z - z_1 )/(z_2 - z_1 )
2. Compute Dot Product/Scalar Product
3. (i) i ̂ .i ̂ = j ̂ .j ̂ = k ̂ .k ̂ = 1
(ii) i ̂ .j ̂ = j ̂ .k ̂ = k ̂ .i ̂ = 0
4. Compute Cross Product/Vector Product
5. Conversion of Cartesian Equation into Vector Equation
6. S.D. between skew lines
7. S.D. between parallel lines
8. If S.D. = 0 then given two lines are coplanar
9. If S.D. = 0 then given two lines are intersecting
10. Length of a vector
