derivative

Measures how quickly a function changes; geometrically it gives the slope of the tangent to the curve, and in applications it represents an instantaneous rate of change.

gradient

The coefficient

a

y=ax+b

, giving the predicted change in

y

when

x

increases by

1

limit

The value that an expression approaches as the input approaches a specified number or tends to infinity, used to describe behaviour near a point or at an asymptote.

tangent

A line that touches a curve at a point and has the same local slope as the curve there, used to interpret the derivative at that point.
