2. Research: Gather information and constraints related to the problem.
3. Specify Requirements: Outline criteria for success and constraints.
4. Brainstorm Solutions: Generate a range of possible solutions.
5. Develop and Prototype: Create models or prototypes of the best solutions.
6. Test and Evaluate: Conduct tests to evaluate prototypes against requirements.
7. Refine and Improve: Analyze test results and make necessary adjustments.
8. Present Solution: Communicate the final design and its benefits.
Importance: Ensures effective problem-solving and innovation in engineering projects.

Mathematical Modeling

Definition: The use of mathematical language and techniques to represent and analyze real-world situations.
Process:
1. Identify the Problem: Determine the situation or phenomenon to model.
2. Construct a Model: Develop mathematical equations or simulations that represent the system.
3. Analyze the Model: Use mathematical tools to study the model's behavior and predictions.
4. Validate the Model: Compare model predictions with real-world data to check accuracy.
5. Refine the Model: Adjust the model based on analysis and validation results.
6. Implement the Model: Use the model for decision-making or further research.
Applications: Used in fields like physics, economics, biology, and engineering for predictions and optimization.
Importance: Provides insights into complex systems and aids in decision-making processes.
