First-order information

First-order information is a term used to mean information obtained by computing the first derivative of a function. The first derivative of a function reveals the slope of a tangent line to the function. This gives a general idea of how the function is changing at that point, but does not give information about the curvature of the function–the second derivative is required for that.

First-order information should not be confused with first-order logic.
