Hey everybody, first time poster although I've recently come across this forum and it's helped me discover the solution of many problems I've been having. I've seen to come to grips with most partial derivative problems I've come across, however, i still can't get correct solutions to problems involving quotients, don't know how exactly to go about it. The two specific questions I've got in my book which i can't seem to get are given below.
Evaluate the first partial derivative
f(x, y) = (x + y)/(x - y) (1)
f(x, y) = log(1+x) / log(1+y) (2)
Thanks for any help which could be given =)
I assume you use the standard quotient rule, but i don't know how exactly to go about it with multiple variables...thanks.
