Pythagoras' theorem and the second cosine formula are well known. The former is the special case of the latter and taught in the junior high school. The latter and the first cosine formula are taught in the highschool. In this paper, we prove the first and the second cosine formulas using the concept of the vector and generalize these formulas. First using the concept of p-vector and *-operator we show a simple formula ofthe normal vectors to the boundary of a simplex, from which we get the generalized cosine formula. Next we invesigate the relation between Gauss' theorem and the above simple formula.
