Hi

I am working on a question that simply states:

Differentiate and Integrate the following functions...

..f(z)= 1/x^(2)

If I am meant to differentiate with respect to z then do either:

(i) leave the x term as it is;
(ii) not include the x term as differentiating with respect to z does not yield anything (which I think the correct approach); or
(iii) something different?

Just to clarify there is no z term in the equation, it is exactly as I have written it.

Thanks in advance,

Kind regards

If you have copied this correctly or it is not a simply a typo the the answers are:
Derivative: $\Large 0$,___________Integral: $\Large\dfrac{z}{x^2}$

Thank you. I triple checked it was not a typo. I did wonder if it was a typo on the worksheet.
