o T-Mobile 9:55 AM Course Messages 1 out of 1 points Question 15 In polynomial curve-fitting, the higher the order of polynomial is the more reliable the curve fit becomes. Question 16 1 out of 1 points In order to generate the following plot in MATLAB, certain commands are needed to divide the plot area and designate the location of the plot being edited. What should be [command A]? 05 >> x#linspace (0,6) ; >> [command A] >> plot (x, sin(x)); >> [command B] >plot (x, cos (x)) Question 17 1 out of 1 points Golden section method can be implemented for maximizing a function fx) within an interval of x, xul as illustrated in the figure. After one iteration, what would be size of the new interval containing the optimum? Note that the golden ratio is p-1.6180. Jix)Explanation / Answer
15: FALSE
Because as the order of the polynomial increases it becomes more squiggly (i.e irregular or with twists) so picking an order too high over fits the data. increasing the order over the best fit curve will decrease the reliability of the curve.
16: MATLAB code for getting a plot as shown is given below:
......................................
x=linspace(0,6);
subplot(1,2,1) %plot first plot in 1x2 grid
plot(x,sin(x));
subplot(1,2,2) %plot second plot in 1x2 grid
plot(x,cos(x));
.....................................
Command A : subplot(1,2,1)
command B : subplot(1,2,2)
