## anonymous one year ago For increments in calculus which notation is prefered, lower or uppercase delta? Where does the different notations come from?

1. anonymous

i.e $\delta x$ or $\Delta x$

2. sparrow2

as i remember they come from leibniz and newton, i think the first one was used by newton and they are the same(do not have any value which you use)

The first one looks cooler though I might be biased, I guess the second one is easier to draw? XD

The second one is the standard. I have never seen the first one. $$\delta$$ is used in advanced calculus to mean a very small distance. There is a small difference here (no pun intended).

It might just be my teacher's choice :D

6. anonymous

I personally prefer the first one in expressing perturbations
