A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees.
In the previous section we saw limits that were infinity and itâs now time to take a look at limits at infinity. By limits at infinity we mean one of the following two limits. In other words, we are going to be looking at what happens to a function if we let x get very large in either the positive or negative sense.
Whenever a point x is within Î´ units of c, f(x) is within Îµ units of L. In calculus, the (Îµ, Î´)-definition of limit (epsilonâdelta definition of limit) is a formalization of the notion of limit. The concept is due to Augustin-Louis Cauchy, who never gave an ( Îµ, Î´ {\displaystyle \varepsilon,\delta } ) definition of limit in his Cours d'Analyse, but occasionally used Îµ, Î´ {\displaystyle \varepsilon,\delta } arguments in proofs. It was first given as a formal definition by Bernard Bolzano in 1817, and the definitive modern statement was ultimately ...
