Calculation of the value of the functions of the complex variable with by an interval argument, we will design in the hyperbolic form

Information about the interval numbers presented in classical form, CENTER-RADIUS system and hyperbolic form is given. Rules for transition from one of forms representation to others are proposed. given on complex numbers, real imaginary parts which form. The rules performing basic arithmetic operations with these calculation values power, exponential, logarithmic functions, direct inverse trigonometric functions described. For a variable, information their list corresponds variable included EXCEL system. Relationships obtained determining secant, cosecant, tangent cotangent circular were absent most common reference literature. It shown that multiplication, division raising an integer power appropriate perform defined operation calculating root degree n number expediently performed using combination representing number. make it possible obtain function equivalent original suitable further work Examples illustrating application proposed technique
