Options
- A0
- B2
- C1
- D4
Correct answer
A. 0
Step-by-step solution
Let aligned I &= ₀^ 2 1- x cosec x+ x d x I &= ₀^ 2 1- x x 1 x + x d x= ₀^ 2 x- x 1+ x x d x ...(1) I &= ₀^ 2 ( 2 -x )- ( 2 -x ) 1+ ( x -x ) ( 2 -x ) d x I &= ₀^ 2 x- x 1+ x x d x ...(2) aligned Adding equations (1) & (2), we get array l 2 I= ₀^ 2 x- x+ x- x 1+ x x d x 2 I=0 I=0 array
