Suppose that ;
1) such that :
2)The Euclidian norm of a vector is defined as :
3) The maxnorm of a vector is defined as :
Where belong to the real Nos R
Then prove :
,with respect to both norms
I know that i have to prove the following:
1) given ε>0 ,i got to find a δ>0 ,such that :
if 0<|x|<δ , then
2)given ε>0 ,i must find a δ>0 ,such that:
if 0<|x|<δ ,then .
Any suggestions for that delta??
