Why would too much oxygen cause a mass extinction 2.2 billion years ago?
Why would too much oxygen cause a mass extinction 2.2 billion years ago? Geological, isotopic, and chemical evidence suggest that biologically-produced molecular oxygen (dioxygen, O2) started to accumulate in Earth’s atmosphere and changed it from a weakly reducing atmosphere to an oxidizing atmosphere, causing many existing species on Earth to die out. What was the […]

How do you know if a limit is one sided?
How do you know if a limit is one sided? A one-sided limit is the value the function approaches as the x-values approach the limit from *one side only*. For example, f(x)=|x|/x returns -1 for negative numbers, 1 for positive numbers, and isn’t defined for 0. The one-sided *right* limit of f at x=0 is […]
