## Homework Statement

find ⌠cotx using integration by parts with using u= 1/sinx and dv= cosx

## Homework Equations

cotx=cosx/sinx

## The Attempt at a Solution

u= 1/sinx and dv= cosx dx

du = -cotxcscx dx v= sinx

⌠udv = 1 + ⌠sinx cotx cscx

sinx and cscx cancel out.

⌠cotx = 1 + ⌠cotx

I=1+I

0I=1?
