I have a problem in chain rule when u and v are again the functions of x,y,z

[@ayantayyab7259]

Sir i think delu/delz should be 0 because it means that we have to differentiate u by keeping x and y as constant and z is a fxn of x and y so z is also constant due to this so del (constant)/delz=0

[@deepmahanta9376]

Sir i have a doubt , why are we taking z as a function of x and y ?

[@mathemusic777]

Its multivariable
