Modifikasi Aturan Trapesium Menggunakan Interpolasi Spline Kuadrat

The final project discusses the quadratic spline rule to solve quadrature problems. A given function f(x) is interpolated by the interpolation quadratic spline then it is integrated. Computational examples show that the solutions of the quadratic spline rule are better than the comparation rule to approach the exact solution. Keywords: Quadrature, trapezoidal rule, quadratic spline rule
