Abstract: In this paper a new two element function is developed based on the properties of paper [ 1] . With this, we discuss the critical tangent points of this function. The theorems and corollarys in this paper are improvements and extensions of the related conclusions of [ 1] , depending on the C2 class surface point's classification.

Key words: critical tangent point, degenerative critical tangent point, critical point
