That's not a delta: the top of the Greek lower-case delta tails off to the right. A partial d is just a funny d that slopes off to the left.

Fyo, Neil is right. That's not a lower case delta but an partial sign (it's used for partial differentations). It's a special 'd' but has no real name. In LaTeX it's called \partial. Lower case deltas are only used for the variation of a given variable. Look for books about Hamilton principle (delta S = 0).
