## Homework Equations

Chain rule from multivariable calculus.

## The Attempt at a Solution

I have tried doing the obvious: multiplying the given numbers, but I am just confused by what F_u and F_v at 5,3 means.

Instinct tells me the question requires F_u at (1,0), multiplied by u_s at (1,0), but none of the answers I've tried have worked. I am more confused by the way this question is asked because I understand multivariable chain rule quite well already to do most other questions.
