I've had recurrent lumps under my armpit.. sometimes translating into an abscess. For the last month, I've been having pain under my right armpit with a seemingly tender spot. Having slight difficulties to lift my hand sometimes and while sleeping my index sometimes became numb. After one month, it became an external bump. Now it kind of fissured and is discharging small amounts of pus along a putrid / rotten smell with a very small protrusion of slightly bleeding body tissue. (Past 3 days)

Why is there a negative part in the graph if I must take absolute values? Shouldn't it be an all positive graph?

I can't figure it out. I know i should use the complex logarithmic function, but i can't work it out. :S

I'm having so much probs to solve this..

integral of

(4-x-y) dx dy

from √(4-y^2) to 0 ((inner limits)

from 2 to 0 (outer limits)

answer = 4π - 16/3

I think it is worked by prime factorization, but i am not grasping the notion. :/ If anyone could detail the proof, it would be of great help to me! Thanks a lot!

I've tried so many times.. :(

I've reached till here :

x^2/2 tan^(-1)⁡3x- ∫ 3/(1+ 〖9x〗^2 ) * x^2/2 dx

don't know how to proceed from here!
