Functions classes

Functions classes

1. Algebraic

   • In algebraic operations functions to be performed with the independent variable They are: addition, subtraction , multiplication , division, empowerment and establishment . functions algebraic include:
     • explicit functions
       • In the explicit functions can be obtained images of x by simple substitution.
         • f(x) = 5x - 2
     • implicit functions
       • En las funciones implícitas no se pueden obtener las imágenes de x por simple sustitución, sino que es preciso efectuar operaciones.
         • 5x - y - 2 = 0
   • polynomial functions
     • Polynomial functions are defined by a polynomial. His domain is R, that is, any real number has image.
       • constant functions
     • First-degree polynomial functions
       • linear function
       • affine function
       • Identity function
   • Rational functions
   • Radical functions

2. transcendental functions

   • Exponential function
   • logarithmic functions
   • trigonometric functions
     • The trigonometric functions associated with each real number x, the value of the trigonometric ratio of the angle whose radian measure is x.
       • Tangent function
         • secant function
           • cotangent function
             • cosecant function
               • Sine function
                 • f(x) = sen x
               • f(x) = cosen x
             • f(x) = tg x
           • f(x) = sec x
         • f(x) = cotg x
   • In transcendental functions independent variable appears as exponent, or as an index of the root or the logarithm is affected either sign or signs used trigonometry.
