∫ [ƒ(x)] dx .....[.] denotes G.I.F.

Q2. ₀∫¹ sin([x]+[2x]) dx =

(A) sin 1 (B) sin(3/2) (C) (sin 1)/2 (D) (sin 2)/3

( [.] denotes G.I.F. )

Q3. _-1∫¹ [|x|] d(1/(1+e^-x)) =

(A) -3 (B) -2 (C) -1 (D) none of these

( [.] denotes G.I.F. )

it reduces to ∫1+[1/(x²+1)]...now can u do it?????[12]

1) (d)
tell me the answer of 1st

1st ans is (__)[3][3]

ya d) for 1st..........

you are absolutely (wrong) = right[4]

3)

hey for 2nd question is the lower limit n or 0........
