Thread: URGENT !!! need help with these 3 integrals problems

Here is the first one.

Here is a response to 3.

I am confused about 2).

I think you mean,

S:x^2+y^2=z^2

Not a^2.

Since a, z are located next to each other on a standard keyboard.

Hi, Thanks a lot for your quick reply. I think I'm required to find a function f that satisfy the given theorem. I'm pretty confused about the question too.

It is a^2. It stands for radius for example, in the parametric equation : x^2 + y^2 + z^2 - a^2 = 0 where a is the radius with centre 0.
