Math 252 Lecture 02: Wednesday, January 6th 1999.

Homework assignment 01 was given.

The results of Monday's quiz were summarized.

Some basic definitions were given. Vectors were defined in general for an n-dimensional space. Scalar Fields and Vector Fields were also defined in terms of an n-dimensional space. The dot product and length of a vector were defined. The geometrical interpretation of the dot product was considered, and a proof of its scalar invariance was given for 2 and 3 dimensional space.
