Question

Use the change of variables s = 1/r and t = θ to transform and evaluate the polar coordinate integral of (1/r3)*r*dr*dθ over the infinite region R where r ≥ 1 and 0 ≤ θ ≤ 2π to an iterated integral over a finite region.

Answer 1

i dont think id even have a clue right now how to approach this

Answer 2

polar stuff is not a sure concept for me since I rarely have the opporunity to practice them
