The maximum of relative errors of each access in Example 1. Example 2 [8] Consider the following ODEs of the 3-DOF system shown in Figure 4: with initial condition and Where , A 15th order Legendre approximation to f (t) is performed. The criterion of least square approximation is taken as a rough estimate of ξ i.e. ε=ξ =≈4.94e-7.

The linear approximation can be used to approximate functional values that deviate slightly from known values. The following example illustrates this process. Example 1: Use the linear approximation of the function at to approximate . Solution: We know that . So we will find the linear approximation of the function and substitute values close to

Using least square fit, find the best approximation to a and b. 8. 4 pts. into HW . The inner product is a very powerful tool that enables us to control the geometry of . R. n. Different inner products on . R. n lead to different measures of vector norm, angle and distance – that is, to different geometries.

The first step in finding the least square line is to construct a sum of squares table to find the sums of x values ( x), y values ( y), the squares of the x values ( x2), the squares of the x values ( y2), and the cross-product of the corresponding x and y values ( xy), as shown in the following table:
