> Anyway, point is mathematics is a language. Yes, and like any language there is context-dependence. In calculus you're right, epsilon and delta are usually small variations (for example in the definition of a limit). In randomized algorithms, if you say epsilon-delta anybody will immediately associate delta with an error probability.
