17.7. Use the golden search method to find the minimum point of the following functions in the interval of 1 x 10. We assume the convergent tolerance is ?,-0.0001. Function (a):f(x)=x2 +500e Function (b):f(x)-x2-e 17.8. Use the gradient-based method to find the minimum point of the same objective functions (a) and (b) as Problem 7. We assume the initial design is given at and convergent tolerance is ?,-0.0001. Use a proper method to determine the step size
