1. ## Simplifying Help

Okay so here's the background.

g=(4pi^2/T^2)l

The instructions are:
Estimate the uncertainty in g using the uncertainty propagation for a general function. The specific formula you should obtain for delta g is:

#1 Δg= g (sqrt(Δl/l)^2 + (2 ΔT/T)^2)

The uncertainty equation is :

#2 ΔF=(sqrt (partial derivative of x)^2( Δx)^2 + (partial derivative of y)^2( Δy)^2)

So basically, make equation #2 look like #1, and solve for delta g.

So the question is, how do I simplify equation #2 to look like equation #1.

F=g , x=l, and y=T is those equations.

2. What did you get for the partial derivatives of g with respect to x and y?

3. ## Partial derivative

The partial derivative of x (l in the equation of g) is 4pi^2/T^2
the partial derivative of y (T in the g equation) is -8pi^2•l/T^3
