Re : LF: Math Question, possible ROM error..?



i think the question has no object: the function sqrt( ) is defined from 0 to
+infinite...
it is defined as the inverse function of x^2 on a domain on which x->x^2 is
bijective... (ie: [0,+infinite) ) 
thus, we have sqrt(0)=0 
we know that sqrt is continuous on [0,+infinite) ( because x->x^2 is C1: its
inverse on an interval is C0 ) 
thus, by the def of the continuity, lim( sqrt(x)), x->0 = 0

well: i think i am right.... but i haven't been doing maths for a month...
and i forget fast... i will look at my lessons later..
