## Homework Statement

Assume that you are given differentiable function f(t) and g(t). Find a formula for the

derivative of the cross product u(f(t)) x v(g(t)).

## Homework Equations

d/dt(u(t) x v(t)) = (u'(t) x v(t) + u(t) x v'(t)

## The Attempt at a Solution

So in this case I was thinking that you would just substitute f(t) and g(t) where t would be in the regular equation, so it would be U'(f(t)) x v(g(t)) + u(f(t)) x v'(g(t)), for the equation, but I have a feeling that that's not right just because it seems too simple.
