#1 Posted 1:03pm 07-03-10 TOUGH INTEGRAL( REALLY )question is as mentioned by SR (SEE DOWN) ANS ----> cot A { log sec(x+A) - log sec x}
In every loss, in every lie, in every truth that you'd deny
And each regret and each goodbye was a mistake too great to hide
And your voice was all I heard that I get what I deserve
