Q2. Determine the positive roots of the simultaneous nonlinear equations: yx2 y 2 cosx Use a graphical approach to obtain your initial guesses. Plot both the equations in one plot area. You may have two sets of solutions. Considering one of the solutions and selecting initial guesses close to that solution (you can take x = 0.7 and yo = 1.5), use Newton-Raphson Method to solve the system of equations, shown above.e, 0.01 %

Newton invented the Newton-Raphson method for solving an equation. We are going to ask you to write some code to solve equations. To solve an equation of the form x2-3x + 2-0 we start from an initial guess at the solution: say x,-4.5 Each time we have the i'h guess x, we update it as For our equation,f(x) = x2-3x + 2 andf,(x) = 2x-3. Thus, our update equation is x2 - 3x, 2 2x, - 3 We stop whenever...
