Unformatted text preview: (a) Determine the critical point(s) of f . (b) Show that the bilinear form D 2 f ( a ) is semideﬁnite. Use directly the deﬁnition of positive/negative (semi)deﬁniteness of bilinear forms. Do not use the criteria that we did not prove in the class. (c) Along the direction vectors for which the strict deﬁniteness is broken, investigate if f increases or decreases. Ferit ¨ Ozt¨urk, Bo˘gazi¸ci University 2006...
