Explain using Matlab code but also why you used the linear system please 1 Quadrature Rule A quadrature rule is a way to approximate integrals numerically i.e. using a computer). Many such quadrature rules can be derived by solving a simple linear system. Set up a linear system and then use Matlab to find the coefficients wo, W1, W2, W3, W4, W5 such that | f(x)dx = wof(0) + wif(0.2) + w2f(0.4) + w3f(0.6) +w4f(0.8) + w5f (1) for each...
3. (1 point) This is 2-point Gaussian Quadrature for any f(x) dx. The weights and the nodes do not change when we integrate a new function. So...does it work? Does this actually lead to a method that is good for intergating functions in general? Use 2-point Gaussian quadrature to approximate the following integral: I e-ra da. -1 The exact value of this integral rounded to 2 decimal places is 1.49. Show your work when computing the approximation. Report the answer...
