## Did I use the right derivative symbol?

The sorts of integral that are being used here are a bit unusual (differentiating one function with respect to another function of the same variable). As such, I'm unclear on whether `dx`

or `∂x`

is more mathematically correct (and used the latter because it's a lot easier to parse). However, if the notation is wrong, I'd want to fix it. Any mathematicians out there able to answer this? --ais523 19:10, 5 February 2019 (UTC)
