If f : R → R is a function, then we write limx→a f(x) = L to mean: ∀ > 0 ∃δ > 0 ∀x ( (0 < |x − a| < δ) → (|f(x) − L| < ) ).

Sequence and Series

A sequence is defined as a collection of things. Series is defined to sum the things one by one in the sequence.  It was invented by German mathematician Carl Friedrich Gauss.
