1. ## derivative

hi, i do not really understand
this at all. If anyone can help
me i'd really appreciate it!

find the derivatives of y=fg/h in terms
of f, g, h, f prime, g prime, and h prime
where f g h are functions of f.

Let u = fg and v = h so that y = u/v. Now differentiate using the quotient rule. To differentiate u = fg you will have to use the product rule.

3. okay thanks. but by applying the product
and quotient rules would that be in terms
of f g h and f1 g1 h1 ?

Do as suggested and you won't need this question answered.
