How To Solve These Equations? Need A Clue/Hint

[mymachine]

Homework Statement

F(t)=

\frac{1}{6}(7-t)^{2}(1,2)+\frac{1}{3}(-t^{2}+12t-34)(3,5)+\frac{1}{6}(t-5)^{2}(6,2)__________if__________5≤t<7

and

\frac{1}{3}(8-t)^{2}(3,5)+\frac{1}{3}(-2t^{2}+30t-110)(6,2)+\frac{1}{3}(t-7)^{2}(9,4)<br />__________if__________7≤t≤8

Homework Equations

None

The Attempt at a Solution

None because I don't understand

I wouldn't ask if I do understand.

This is a spline equation.

Thank you

The title of you thread mentions "solving these equations", but there's nothing to solve.

It looks as though F(t) is a piecewise defined function.

Are the quantities which look like points actually supposed to be position vectors? (I'm referring to (1, 2), (3, 5), and (6, 2) in the first expression.)

I am not sure.

Yes, it might be.

It looks like a cartesian coordinate to me.

What should I do?

Should I multiply them?

Note this is a function of spline.
