If 0 x 1 , I₁ = ⁻¹ 1-x^2 ,dx and I₂ = ⁻¹x ,dx , then which of the following is true?

Options

  1. AI₁ = I₂
  2. BI₁ = 2 I₂
  3. CI₁ + I₂ = 2 x
  4. DI₁ + I₂ = 2

Correct answer

C. I₁ + I₂ = 2 x

Step-by-step solution

For 0 x 1 , the inverse trigonometric identity is: ⁻¹ 1-x^2 = ⁻¹x Substituting this into I₁ : I₁ = ⁻¹x ,dx Given: I₂ = ⁻¹x ,dx Adding I₁ and I₂ : I₁ + I₂ = ⁻¹x ,dx + ⁻¹x ,dx I₁ + I₂ = ( ⁻¹x + ⁻¹x) ,dx Using the identity ⁻¹x + ⁻¹x = 2 : I₁ + I₂ = 2 ,dx I₁ + I₂ = 2 x Answer: I₁ + I₂ = 2 x
