Proceedings of the American Mathematical Society, Vol. 36, No. 2 (Dec., 1972), pp. 485-490 (6 pages) This paper is concerned with differentiation of interval functions appearing in interval analysis.

Research in inequalities and integrals within the realm of fuzzy and interval-valued functions has advanced our understanding of uncertainty quantification and non-linear analysis. This field ...

Interval-valued optimization problems constitute a rapidly evolving field in applied mathematics and engineering, addressing situations where uncertainty and imprecision are inherent in model ...

Additivity: If f is integrable over intervals [a, b] and [b, c], then f is integrable over [a, c], and the integral over [a, ...

Methods described first by Madansky (1965) and revived more recently by Cox & Oakes (1984, pp. 51-2) are extended to incorporate the calculation of likelihood-based confidence intervals for functions ...

Problem Type 1 typically involves graphing piecewise functions with relatively simple sub-functions, such as linear functions, constants, or simple quadratics. Here’s a structured approach to graph ...
