Let I₁= ₀^1 ⁻¹ ( x 1+x^2 ) d x ; I₂= ₀^1 ⁻¹ ( x 1+x^2 ) d x and I₃= _ n ( 1 n+1 + 1 n+2 + + 1 2 n ) , then:

Options

  1. AI₁+I₃=I₂
  2. BI₁+I₂+I₃= 2
  3. CI₂+I₃=I₁
  4. DI₁+I₂+I₃= 2 + 2

Correct answer

D. I₁+I₂+I₃= 2 + 2

Step-by-step solution

aligned & I₁= 4 - 1 2 2 & I₂= 4 + 1 2 2 & I₃= 2 aligned
