Question

transformation: x=2u y = 3v
double integral (x^2 y) dA
equation: 9x^2 + 4y^2

Answer 1

Apa kabarnya IPB? :D

Answer 2

9x^2 + 4y^2=36
36u^2 + 36v^2 = 36
36 (u^2+v^2) = 36

jacobian = 6

\[\int\limits_{o}^{2\pi}\int\limits_{0}^{1} 36r^2 r dr d \Theta\]
is it true my double integral?

Answer 3

woah ada orang indo, seperti biasa aja ipb, lagi rame penerimaan 48

Answer 4

In the original integral what is A?

Answer 5

area?

Answer 6

I mean usually we compute the double integral over some area A (or S usually). What is the area? is it a cicle, area bounded by some curves or what?
