In this question , limit of dz will be fixed . Order of z can not be changed neither with x nor y bcoz z has no independent limit with x or y in zx or zy plane . we can change order of integration between x and y only .
Deepak sir, how do you know that z is a dependent variable on x,y??
.
sir, please tell me why do you think that z cannot be expressed as a function of x,y? like we do x=y+7 as y=x-7 similarly we can do this for 2 variable functions can't we??
even the answer comes out the same i.e. 1/12.
