## Homework Statement

Show

[tex]

\partial /\partial u \int_{a}^{u} f(x,v) dx = f(u,v)

[/tex]

## Homework Equations

## The Attempt at a Solution

Basically i understand that we hold all other variables constant, and i understand that we will get our answers as a function of u and v. But to show that we have f(u,v) im not too sure

[tex]

\int_{a}^{u} f(x,v)dx

= g(u,v)- g(a,v)\\

[/tex]

[tex]

\partial /\partial u [g(u,v)- g(a,v)]= g'_{u}(u,v)
