- 30

- 0

and outside the curve [tex] r = 3-1*cos(\theta)[/tex]

when i plugged those two functions into my calculator and found the bounds from 1.0471976 to 5.2359878.

my integral:

[tex] \int_{1.0471976}^{5.2359878} 1/2*(5*cos(\theta))^2 - 1/2*(3-1*cos)^2[/tex]

and got a final answer of

-4.10911954 which is incorrect. anyone know what i did wrong?
