∫ [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]

I know how to do these....it's just for others to try!!

chalo ek hi reh gaya tha
