Students can benefit from error checking by learning where they went wrong and fixing it before submitting their work.

Students' ability to think critically and find solutions to problems is enhanced by the process of checking for faults. Error checking is a skill that calls for analysis, focus, and the ability to spot typos. Students can get insight into their own thought processes and develop as problem solvers if they take the time to check their work for flaws. Students' self-assurance might also grow as they become more familiar with the benefits of error checking. Students might gain self-assurance in their work and do better academically when they verify that their solutions are free of mistakes.

Finally, error checking can aid students in comprehending the system's operation. Incorrect solutions can sometimes lead to unachievable mathematical or physical outcomes. Students can get insight into the system's quirks and learn how to prevent such mistakes in the future by actively seeking out and reporting them. In addition, having students perform error checking might help them appreciate the benefits and drawbacks of MATLAB solvers. Students can solve future ODEs with more assurance if they are aware of these restrictions and use an appropriate solver.

## Reduce the Problem’s Complexity

When using MATLAB to solve ODEs, simplifying the issue often yields better results. Some problems involving ordinary differential equations (ODEs) may appear complex and difficult to answer at first look, but students can reduce the complexity and make the problem easier to solve by using appropriate simplifications. Assumptions, approximations, or transformations may be used to reduce the complexity of the problem. The issue can be simplified and made easier to answer by employing several techniques, such as assuming that some parameters are constants or approximating the solution with a Taylor series. In order to solve ODEs, it is necessary to first reduce the complexity of the problem.

Simplifying the problem also aids students in comprehending the system's behavior, which is a crucial consideration. Students can learn more about the system and its impact on the solution if the problem is broken down into its component parts. Students can use this method to hone their instincts concerning ODEs and their applications. Students may be better able to recognize the limitations of the answers if the problem is simplified. Students can gain a deeper awareness of the complexities of real-world problems and the need for more precise and efficient solutions by being familiar with the constraints of existing approaches.

Last but not least, students can save time and energy by reducing the complexity of the problem.
