Question

Hi everyone, I need help with automata, please

 

### Problem Statement:

Given the description of \( L_1 \) and \( L_2 \) as regular languages in the form of acceptors \( M_1 \) and \( M_2 \). Show that the following languages are regular by constructing an automaton using generic descriptions of \( M \) below:

![Diagram of a generic automaton \( M \) consisting of a start state leading to a series of transitions, ending in an accepting state.]

### Tasks:

(i) Demonstrate that \( L_1 \cup L_2 \) is regular.

(ii) Demonstrate that \( L_1 L_2 \) (concatenation) is regular.

(iii) Demonstrate that the complement of \( L_1 \) is regular.

### Explanation of Diagram:

The diagram is a generic representation of a finite automaton \( M \). It begins with a start state, represented by a circle with an arrow pointing to it. This state leads to a succession of states highlighted by lines with wave-like transitions and ends in a double-circle, indicating an accepting state. This generic sketch serves as a foundation for constructing specific automata that satisfy the conditions of regular languages \( L_1 \cup L_2 \), \( L_1L_2 \), and the complement of \( L_1 \).
