Composite quadrature (rectangle, trapezoidal, Simpson's, Newton–Cotes, Gauss–Legendre) with relative error analysis.

Numerical Methods Assignment: Implementation and analysis of Romberg Integration with comparison to Simpson’s and Trapezoidal rules, including error and convergence analysis.

C++ implementation of Numerical Methods and Scientific Computing algorithms including Bisection, Newton-Raphson, fractals, complex roots, Trapezoidal and Simpson integration methods, Euler, RK2, RK4 ODE solvers, and interpolation techniques such as Newton, Lagrange, Forward, Backward, and extrapolation methods. For plots we used GNUPLOT in LINUX
