is the limit of a constant as x--> infinity 0?

8 years agoconstant

8 years ago$$(\forall \epsilon>0)(\exists \delta>0)\rightarrow \left| f(x) - c \right|<\epsilon$$

8 years ago$$f(x) = c $$

8 years ago$$\left| c-c \right|=0<\epsilon, 0<\delta<\epsilon$$

8 years agowell that proved it if you're going to zero, my bad

8 years agoI don't think so

8 years agoyou don't think so what? That proves it for any finite x. The infinite proof is slightly different

8 years agoconstant is constant always it will not change anymore regarding a change of anything change in climate doesnot change the position of a tree. it is constant. so limit of a constant is constant always not zero

8 years agonoufal i don't think you understand delta-epsilon proofs, with the wording of your response. And the limit of a constant is zero if the constant is zero.

8 years agoThe limit of a constant as x approaches infinity is that constant. This can be shown using delta-epsilon.

8 years agowhich is what i proved above for finite x. The infinite proof is: \[(\forall \epsilon>0)(\exists N>0)(\forall x>N)(\left| f(x)-L \right|<\epsilon)\] f(x) = C and L = C, so \[\left| f(x)-L \right|=\left| C-C \right|=0<\epsilon\] so any x>N may be chosen to satisfy the proof.
