In mathematics, a procedure for determining the derivative or gradient of the tangent to a curve f(x) at any point x.
The derivative may be regarded as the limit of the expression [f(x + dx) - f(x)]/dx as dx tends to zero. Graphically, this is equivalent to the gradient (slope) of the curve represented by y = f(x) at any point x.
The mathematical process of obtaining the derivative of a function. + prikaži više
