WildLinAlg9: Three dimensional affine geometry

Three dimensional affine geometry is a big step from two dimensional planar geometry. Here we introduce the subject via a 3d coordinate system, showing some ZOME models, explaining how to draw such a coordinate system in the plane, and seeing how points in space are naturally associated to triples of [x,y,z] of numbers. We discuss points, lines and planes in 3D, and point out the important distinction between affine space and a vector space.

helpful... thanks for your patience in going thru this in detail

Hi Norman,

Your book just landed on my welcome mat this morning... started reading it today ..

I have watched linear algebra lectures of MIT and others and find your lectures far more understandable... well done..

Why have we waited so long for mathematics to become type driven? Other lectures seem so disjointed and confusing... you seem to have cracked it.

Kind Regards

Graham

btw ... get a good razor... :)

yes, indeed addition of two points in affine space is not defined.
