MathSeque

Mathematical and popular science iOS application. Covering classic sequences such as Catalan numbers, Bell numbers, two types of Stirling numbers, Euler numbers, etc., it provides functions such as numerical calculation, interval adjustment, triangular matrix visualization, recursive relationship diagram, combination meaning analysis, and prime modulus operation analysis. It is equipped with interactive controls such as sliding and stepper, and efficiently completes large number operations and sequence generation through iterative algorithms and dynamic programming. It also adapts to mobile phones and tablets, presenting various combination mathematical formulas, properties, and arrangement rules in a visual form. Lightweight design meets the reference needs of mathematical learning and research.
