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...
