Dual of Linear Programming (LP): The dual of the given LP is another LP derived in the following schematic way from the original (the primal) LP. Every variable in the primal Linear Programming becomes a constraint in the dual LP. Every limit in the primal Linear Programming becomes a variable in the dual LP. In the dual LP, the objective direction is inversed. That is, the maximum in the primal becomes minimum in the dual and vice-versa. Weak Duality: The weak duality is an optimization concept that states that the gap in duality is always greater than or equal to 0. This means the solution to the primary(minimization) problem is always greater than or equal to the solution to a dual problem associated with it.

Dual of Linear Programming(LP):

The dual of the given LP is another LP derived in the following schematic way from the original (the primal) LP.

Every variable in the primal Linear Programming becomes a constraint in the dual LP.

Every limit in the primal Linear Programming becomes a variable in the dual LP.

In the dual LP, the objective direction is inversed. That is, the maximum in the primal becomes minimum in the dual and vice-versa.

Weak Duality:

The weak duality is an optimization concept that states that the gap in duality is always greater than or equal to 0.

This means the solution to the primary(minimization) problem is always greater than or equal to the solution to a dual problem associated with it.

Modular Program Structure. Analysis of Structured Programming Examples. Ways to Reduce Coupling. Based on the given problem, create an algorithm and a block diagram, and write the program code: Function: y=xsin⁡x Interval: [0,π] Requirements: Create a graph of the function. Show the coordinates (x and y). Choose your own scale and show it in the block diagram. Create a block diagram based on the algorithm. Write the program code in Python. Requirements: Each step in the block diagram must be clearly shown. The graph of the function must be drawn and saved (in PNG format). Write the code in a modular way (functions and the main part should be separate). Please explain and describe the results in detail.
