The computation of the first and second order derivatives is used in many applied problems. Let's consider the most common of them.

  • The extremum of a function of one variable is found by equating the derivative to zero: f '(x) = 0. This is the main stage of constructing the graph of a function using the method of differential calculus.
  • The value of the derivative at the point x0 allows us to find the equation of the tangent to the graph of the function.
  • The ratio of the derivatives allows us to calculate the limits by the L'Hospital rule.
  • In mathematical statistics, the distribution density f (x) is defined as the derivative of the distribution function F (x).
  • When searching for a particular solution of a linear differential equation, it is required to calculate the derivative at a point.
  • In the Newton method, using the derivative, the roots of the non-linear equations are separated.
