Step 1  help_outlineImage TranscriptioncloseIt is known that the second partials test for relative extrema is d f(a,b)f(a,b)-[£s(0,b)] 1) If d >0 and f (a,b) >0 then f has relative minimum at (a,b 2) If d 0 and f(a,b) <0 then f has relative maximum at (a,b) 3) If d < lim 0 then (a,d,f(a,b)) is a saddle point. 4) Information when d 0 fullscreen
