Sol. - Yes, I see a 2x2 matrix here. Recognizing the system of equations in matrix form is crucial because it allows us to use matrix operations to solve the system more efficiently, especially when dealing with larger systems. By representing the coefficients of the variables and the constants in matrix form, we can apply many useful techniques to find the solutions. Studying matrices in general is important because they offer a powerful way to represent and manipulate data in various fields. Matrices provide a concise and structured way to represent complex systems and relationships, making it easier to analyze and solve problems. - -When we rewrite the system of equations in matrix form, it looks like the matrix equation mentioned in the question. - -This representation allows us to apply matrix operations to find the solution to the system of equations. -

8.Consider a simple function $$f(x) = 3x+2$$. This function is invertible right? Can you tell us what is $$\alpha$$ such that $$f(\alpha)=17$$? Is such an $$\alpha$$ unique? How did you find such an $$\alpha?$$. Is this always possible? @@ -587,8 +581,6 @@ Therefore, LHS can only be a linear combination of the vectors \((3,1,1)\) and \
Sol. - In situations where a system of equations is overdetermined, as in the case provided, where there are more equations than unknowns, there may not exist a solution that satisfies all equations simultaneously. Consequently, attempting to solve the system by guessing values is unlikely to yield an exact solution. However, we can employ guesswork to minimize the error between the observed and predicted values, effectively reducing the discrepancy between the equations. By iteratively adjusting the guessed values and evaluating their impact on the overall error, we can approximate a solution that minimizes the discrepancy as much as possible. This process, though not guaranteed to yield a precise solution, allows us to iteratively refine the estimates and improve the fit between the observed and predicted values. -
