## Trapezoidal Rule

One of the most popular and straightforward techniques for numerical integration is the trapezoidal rule. Students can use MATLAB to implement the trapezoidal rule algorithm in this assignment to approximate definite integrals. Students can comprehend the significance of subdividing the interval and iteratively calculating the area under the curve by being given a step-by-step guide and real-world examples. They will gain knowledge about how to deal with different interval sizes, assess accuracy, and contrast outcomes with the precise solution. Through this task, students will practice using the trapezoidal rule and hone their MATLAB programming abilities. They will examine the trade-offs between computational efficiency and precision and watch how changing the partition size affects the approximation's accuracy. Additionally, the task may involve exercises where students use the trapezoidal rule to address actual issues, like figuring out the area under a curve or approximating a function's definite integral. Students who complete this assignment will have a firm understanding of the trapezoidal rule and its useful applications in numerical integration.

## Simpson's Rule

Another well-liked method of numerical integration that is more accurate than the trapezoidal rule is Simpson's rule. This assignment focuses on using MATLAB to implement Simpson's rule algorithm. The interval will be broken down into smaller subintervals, the proper formula will be applied, and various integration scenarios will be handled by the students. Students can quickly determine the area under the curve using Simpson's rule by programming in MATLAB. They can test out various functions, investigate the trade-off between precision and computational complexity, and contrast the outcomes with those from other approaches. Exercises involving the application of Simpson's rule to approximate definite integrals and an analysis of the effects of increasing the number of subintervals on the approximation's accuracy can be included in the assignment. The idea of composite Simpson's rule, which entails breaking the interval into equal subintervals and applying Simpson's rule to each subinterval separately, is also something that students can explore. This method makes it possible to approximate definite integrals with complex functions with more accuracy and flexibility. Students will learn more about Simpson's rule and its role in numerical integration as a result of this assignment.

Gaussian quadrature is a technique for numerical integration that used particular weights and nodes to produce results with high accuracy for a variety of functions. Students learn how to implement Gaussian quadrature in MATLAB through this assignment, including how to choose the best nodes and weights. Students will learn about the orthogonality characteristics of orthogonal polynomials and investigate how effective Gaussian quadrature is in comparison to other techniques. The computational capabilities of MATLAB can be used by students to build an algorithm that efficiently performs Gaussian quadrature calculations. Exercises involving the application of Gaussian quadrature to approximate definite integrals and comparison of the outcomes with other numerical integration methods may be part of the assignment. Students can also investigate the idea of adaptive Gaussian quadrature, which increases accuracy by varying the number of nodes and weights based on the behavior of the function. Students will gain a thorough understanding of Gaussian quadrature, its mathematical underpinnings, and its useful applications in precisely computing definite integrals through this assignment.

## Monte Carlo Integration

The probabilistic numerical integration method known as Monte Carlo integration used sampling at random to estimate integrals. Students can use MATLAB to implement Monte Carlo integration in this assignment, and they will also gain an understanding of random sampling, error estimation, and convergence. Students can create a large number of random points within the integration domain using MATLAB's random number generation capabilities, and then use those points to estimate the integral. Students may be required to complete exercises in which they use Monte Carlo integration to approximate definite integrals, analyze the rate of convergence as the number of samples rises, and investigate various sampling techniques, including stratified sampling and importance sampling. Students can also evaluate error estimation methods like the Central Limit Theorem to measure the precision of Monte Carlo integration. Students will gain practical experience with Monte Carlo integration through this assignment and deepen their understanding of its probabilistic nature used in resolving challenging integration problems.

## Romberg Integration

Romberg integration is an iterative technique for numerical integration that boosts precision by combining Richardson extrapolation and the trapezoidal rule. The Romberg integration algorithm can be implemented, the convergence process can be understood, and the error reduction with each iteration can be examined by students as they work on a MATLAB assignment. Students will comprehend Richardson extrapolation and its role in improving the accuracy of numerical integration more fully by applying the Romberg integration algorithm in MATLAB. Exercises, where students use Romberg integration to approximate the definite integrals of various functions and examine how convergence changes as the number of iterations rises, can be a part of the assignment. Students will see how the Romberg integration algorithm converges to the exact solution by improving the approximation with each iteration. They can contrast Romberg integration with other numerical integration techniques in order to investigate the trade-off between computational complexity and accuracy. The iterative nature of Romberg integration and its practical applications in achieving highly accurate integration results will be explained to students in-depth through this assignment.

### Numerical Differentiation and Integration

In this assignment, MATLAB is used to combine numerical differentiation and integration techniques. The Newton-Cotes formulas, error analysis, and the connection between differentiation and integration are just a few of the ideas that students can investigate. Students will gain a comprehensive understanding of numerical calculus by using techniques like the composite trapezoidal rule, composite Simpson's rule, and composite Gaussian quadrature in MATLAB. Exercises using these methods to approximate function derivatives and integrals may be part of the assignment. By contrasting the numerical approximations with the exact solutions, they will examine the accuracy of the approximations and evaluate the effects of increasing the number of intervals or function evaluations. Additionally, in order to quantify the accuracy of the numerical methods, students can investigate error analysis techniques like figuring out the order of convergence. Students will gain a thorough understanding of the interaction between these two fundamental ideas by combining numerical differentiation and integration in this assignment. They will also learn how to use MATLAB as a potent tool for their implementation.

### Application-Oriented Integration

Students have the opportunity to investigate the practical use of numerical integration in this assignment. They can create MATLAB programs to address pertinent integration issues in a chosen application domain, such as engineering, finance, or physics. The importance of numerical integration in various fields will be better understood by students as they apply their knowledge to real-world situations. Exercises where students model and resolve integration issues unique to their chosen application domain may be included in the assignment. For instance, physics students can simulate a particle's motion using numerical integration methods, and finance students can use numerical integration techniques to approximate option prices.
