4 equations and 4 unknowns: , , . But actually there are 3 equations since the diagonal elements of are identical. The 2nd and the third equations are identical. So we need another restriction to solve the relations: (i) Cholesky decomposition: We saw before that this leads to an exact identification. Number of knowns=2(3)/2=3. # unknowns = 22-1=3.

Equations - are a system of 4 equations in the 4 unknowns K, Y, L, C. We can drop equation and the variable C and have 3 equations in 3 unknowns. Reducing the Model to a Univariate Differential Equation. Unlike an ordinary system of equations, this one involves a time derivative – – as well as the levels of the variables.

Estimating and Predicting Unknowns. In this exercise you will use least-squares curve fitting to develop two equations to model the data given. Using these equations, we will predict the function values for two inputs and evaluate the prediction made by each of the curves and linear interpolation. Part A

Use the 5 point star stencil to write a system of 4 equations in 4 unknowns u1, u2, u3, u4. 3. For n=2 use calculus to prove that a potential minimum point of F(u) = (1/ 2 ) uTA u - bTu is the solution to A u = b if A is symmetric. Hint: let , and so that Set the partial derivatives of F with respect to x and y to zero. 4.
