\begin{enumerate}
\item[1.] This is a problem on Gaussian quadrature and related things.
\begin{enumerate}
\item[a.] Explain the principle of the Gaussian quadrature.
\item[b.] Show that the Gaussian quadrature \(\int_{-1}^{1}
f(x) dx = c_0 f(x_0) + c_1 f(x_1)\) can be exact for all
polynomials of degree 3 with 2 points \(x_0 = -
\frac{1}{\sqrt{3}}\) and \(x_1 = \frac{1}{\sqrt{3}}\). Find
\(c_0\) and \(c_1\) as well.
\item[c.] Determine the values of \(c_i\) and \(x_i, i = 0, 1\)
so that the quadrature formula \(\int_{-1}^{1} x^2 f(x) dx =
c_0 f(x_0) + c_1 f(x_1)\) will be exact for all polynomials of degree 3.
