## Homework Statement

Consider the function F(xyz)=x^4+5y^4+2yz+3. Let the uncertainty in x be represented by the variable dx, the uncertainty in y be represented by the variable dy, and the uncertainty in z be represented by the variable dz.

Find an algebraic expression for the uncertainty in the function due to the uncertainty in x

## Homework Equations

Δf

_{x}(x,y,z)=f(x+Δx,y,z)−f(x,y,z)

## The Attempt at a Solution

ΔF

_{x}= [((x+dx)^4)+(5*(y^4))+(2*y*z)+3]-[(x^4)+(5*(y^4))+(2*y*z)+3]

I simply added dx to the variable x although this is not correct
