The value of [ ⁻¹ ( 1-x^2 2 x )+ ⁻¹ ( 1-x^2 1+x^2 ) ] is
Options
- A0
- B1
- C-1
- D1 2
Correct answer
B. 1
Step-by-step solution
The expression E = [ ⁻¹ ( 1-x^2 2 x )+ ⁻¹ ( 1-x^2 1+x^2 ) ] simplifies to a constant through the substitution x = . For x > 0 with (0, /2) , we find that ⁻¹ ( 1-x^2 2 x ) = 2 - 2 and ⁻¹ ( 1-x^2 1+x^2 ) = 2 . Their sum is 2 , yielding E = 2 = 1 . 1
