demonstrate the use of the method with reflections on the use of numerical methods, as described below. As your main task, you seek the minimum for the function below:f(x,y)=Ax^2-Bxy+Cy^2+x-yA= 2 B= -2 C= 1 X0= 4 y0=41.Identify the minimum for the function using the vectoral application of Newton's method while applying dynamic . Thus, you need to optimize for each iteration step to improve performance and avoid overshoot. Use iterations to find the solution with the accuracy of five significant numbers. 2.Identify the minimum again using the Newton's method with dynamic . However, use this time numerical derivatives instead of. When using numerical derivatives, only one of the constants is being varied as with partial derivatives. Apply in this case the forward numerical derivative, . Here equals some very small number. For each step, solve first the and optimal using the condition. When taking the derivative of, please remember to consider the inner derivatives for each of the…
