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.
Again, a limit is a number. (Definition 2.1. ) When we say that f (x) becomes infinite, we mean that no matter what large number you name, it will be possible to name a value of x such that the value of f (x) will be larger than that number.ventually, they become larger than any number we might name. We then say that the values of f (x) become infinite, and that the limit of f (x) as x approaches 0 is infinity. Now, a limit is a number. But infinity, along with its symbol â , is not a number, and it is not a place.
