Plot the functions x(t), vx(t) and ax(t) in same graph and check qualitatively the mathematical relationship between three functions

I have the values of x(t), vx(t), ax(t)

Answer 1

[DGM]

t = linspace(0,1,100);
x = -t.^2;
v = -2*t;
a = -2*t.^0;

h = plot(t,x,'b',t,v,'r',t,a,'m');
legend(h,{'x','v','a'})

How do do this —-check qualitatively the mathematical relationship between three functions

[Walter Roberson]

"qualitatively" means that you describe the relationship. It is not a mathematical measure. Mathematical measures are "quantitative" not "qualitative"

[DGM]

I don't know if the assignment actually is asking for a written answer, but I'll assume it does. If it doesn't, just think about it like this.

What is the conceptual significance of the data in these vectors; in other words, what does it represent? What visually discernable qualities do you expect the plots to reveal? Do the plots look like you expect? Describe why they do or don't.

Think about:

physical relationships -> calculus concepts -> polynomial orders -> basic shape
