Calculation of elementary function values with interval stated argument determined in center-radius system

V.Yu. Dubnitskiy, A.M. Kobylin, O.A. Kobylin
Annotations languages:

Algorithms are proposed to calculate the values of elementary functions whose arguments are represented by interval numbers determined in center-radius system. The arguments are realized in specialized programmable calculator which enables to calculate interval values of power, exponential, logarithmic function, direct and inverse trigonometric functions, direct and inverse hyperbolic functions.
Keywords: elementary functions, interval numbers determined in center-radius system, specialized programmable calculator, exponential, logarithmic function, direct and inverse trigonometric functions, direct and inverse hyperbolic functions
