Comparison between 2-point Gaussian and trapezoidal

quadrature. The blue line is the polynomial

y(z) 7a-8a 3a+3, whose integral in -1,1]

is 2/3. The trapezoidal rule returns the integral of the

orange dashed line, equal to y(-1)+y(1)

2-point Gaussian quadrature rule returns the integral of

the black dashed curve, equal to

y(-/)y()2/3. Such a result is exact,

since the green region has the same area as the sum of

the red regions.
