You can use your standard derivative rules from calculus to find these derivatives. There is no need to replace , just treat as a constant and use the Quotient, Product and Chain rules
Hello, I'm kinda lost with this problem: "Find a derivation of this functions:"
I really don't know where to start, the only thing that comes to my mind is to "replace" with . Can someone help me? I would like to solve it by myself, but I need a little help.
Thank you for your time and help.
Monroe Yoder is right. As long as you have "basic" polynomial, rational, and exponential functions, it does not matter if you have "x" taking real values, or "z" taking complex values, the "rules of differentiation" are exactly the same. For example, the derivative of " " using the product rule, is just
