Homework Statement
As part of an assignment, I have to determine propagated error of some function:
[itex]f(x,t)[/itex]
I did it first with x & t being completely uncorrelated, but now I'm given x as a function of t, [itex]x(t)[/itex], and have to do the same.
Homework Equations
I know the linear approximation for finding the uncertainty [itex]\sigma_f[/itex], all I need is the covariance term.
The equation x(t) itself is simply [itex]x(t) = a \sqrt{t}[/itex], where a is just a constant.
The Attempt at a Solution
I seem to be having a hell of a time Googling to find a way to calculate the covariance between t and x(t).
