what is the definition of a derivative formula. Geometrically the derivative of a function can be interpreted as the slope of the graph of the function or more precisely as the slope of the tangent line at a point. The limit if it exists of the quotient of an increment of a dependent variable to the corresponding increment of an associated independent variable as the latter increment tends to zero without being zero.

Its calculation in fact derives from the slope formula for a straight line except that a limiting process must be used for curves. Geometrically the derivative of a function can be interpreted as the slope of the graph of the function or more precisely as the slope of the tangent line at a point. The definition of the derivative can be approached in two different ways.
Some of the important formulas of derivative are as follows-.
As previously stated the derivative is defined as the instantaneous rate of change or slope at a. Finding the derivative of a function is called differentiation. Derivative Functions The derivative function gives the derivative of a function at each point in the domain of the original function for which the derivative is defined. The derivative of fx is mostly denoted by fx or dfdx and it is defined as follows.
