Hi

I've just done a question regarding a marble moving on a surface given by z = -1/(x

In this case what happens with dimensional analysis ? x and y have dimensions of length while z has dimensions of 1/(length)

Is this question badly written or do i just accept that i won't be able to perform dimensional analysis on any later terms that are produced ?

Thanks
