The terms [[speed]] and [[velocity]] are often used interchangeably, which is incorrect.  [[Speed]] is a [[Scalar quantity]] which refers to the magnitude, or size, of the [[velocity]] [[vector quantity|vector]].  [[Velocity]] has a direction, while [[speed]] does not.

  Given a graph of a [[real]] curve, the derivative at a specific point will equal the [[slope]] of the line [[tangent]] to that point.

To calculate the derivative of a function, one must use techniques from the differential branch of calculus. This branch of calculus is related to the integral branch by the first fundamental theorem of calculus: ''differentiation'' (the process of finding a derivative) ''is the reverse process of [[integral|integration]]'' (the process of finding an integral).
