In most occasions,you can request that your mechanic perform a Block test to ensure their hasn't been any major damage done to your engine, BEFORE you decide to repair the causes of overheating (rubber hose,thermostat,water pump,radiator,cooling fan etc). Sometimes their is no choice ,but to repair the causes first.
Epsilon (uppercase Îµ, lowercase Îµ or lunate Ïµ; Greek: Î­ÏÎ¹Î»Î¿Î½) is the fifth letter of the Greek alphabet, corresponding phonetically to a mid front unrounded vowel /e/. In the system of Greek numerals it has the value five. It was derived from the Phoenician letter He .
The epsilon-delta ordeal is the definition of what we really mean when we say that the limit exists. If we define the word pmmmf to mean x=2, it doesn't make sense to ask how that definition proves that x=2. It doesn't. It just explains what people who use the word pmmmf really mean when they say it.
