Did you draw a sketch?

Did you express u=0 and v=0 in the new coordinates?

Did you express u=0 and v=0 in the new coordinates?

Will I know that in uv coordinates the region is the first quadrant.Did you draw a sketch?

Did you express u=0 and v=0 in the new coordinates?

If u=0, then z=v.

If v=0, then z=u.

Does this help me in any way?

These are not the only options, and you are trying to do two steps at the same time. Do it step by step.If u=0, then z=v.

If v=0, then z=u.

If ##x=0,y \ne 0##, then ##z=y,t=0##These are not the only options, and you are trying to do two steps at the same time. Do it step by step.

If ##y=0,x \ne 0##, then ##z=x, t=1##.

Is this correct?

Sorry, replace x with u and y with v.What are x and y?

And if u=v=0 then z=0.

That looks good and it should tell you what to integrate over.
