A7 – Vectors 4

Lines and planes – here you need to realise <x,y,z>, xi+yj+zk, [x,y,z] and (x,y,z)  are all ways of writing a vector (you can also write them vertically as seen before). Most of the following videos use the square bracket notation, unfortunately this notation can be used to mean the scalar triple product – as is done in MATH1110 – but there shouldn’t be too much confusion since you can determine the meaning of the notation by the context.

Equations of a line

Intersections of lines and planes

Equations of the plane

Intersection of planes

Distance from a point to a plane
